A strong horse-trailer window should match the trailer opening and the way you need to manage airflow, access, and animal security. For horses traveling in a trailer, RecPro Horse Trailer Feeder Window 24×20 stands out with drop-down aluminum bars, an inside screen door, and a trim kit. This roundup also includes a larger RecPro feeder window, horse-trailer-compatible replacement windows, and an emergency-exit model.
The right choice depends on whether you need a feeder opening or a conventional sliding window, plus exact cutout and wall-thickness compatibility. Product dimensions and included parts vary, so check the measurements against your trailer before ordering.
These options are not interchangeable: feeder windows, sliding windows, and emergency exits serve different purposes.
RecPro Horse Trailer Feeder Window 24×20 is the leading choice for horse-trailer use because it combines drop-down aluminum bars with an inside screen door, letting you keep the window open for ventilation while the screen and bars remain in place. Its 24-by-20-inch format and included trim kit make it a practical feeder-window option. If you need a larger feeder opening, consider the 30-by-24-inch RecPro model, but it does not include a trim kit.

Detailed Reviews: Best Windows For Horse Trailers
Why it ranks #1: Made specifically as a horse-trailer feeder window, it pairs drop-down aluminum bars with an inside screen door and includes a trim kit.
An inside-mounted screen door and drop-down aluminum bars let this RecPro feeder window stay open for airflow while retaining a barrier during travel. Its 24-by-20-inch format and included trim kit make it a feeder-window option for trailer owners replacing or adding an opening of the matching size.
The bars provide a safety barrier when the window is open, while their drop-down action supports access for feeding or checking an animal. The screen door is attached inside the window, so you can keep the screen and bars in place as air circulates. Rounded corners give the opening a streamlined profile, and heavy-duty hinges support repeated operation. The package includes a trim kit; confirm the opening dimensions before choosing this 24-by-20-inch window.
- Drop-down aluminum bars provide a barrier with the window open
- Inside-mounted screen door supports airflow with screen and bars in place
- Heavy-duty hinges support repeated opening and closing
- Trim kit included
- The listed 24-by-20-inch size may not suit openings requiring a different feeder-window dimension.
Skip it if you need a 30-by-24-inch feeder opening; the RecPro B07MTKCQRY has the larger listed size.
Choose this RecPro for a horse-trailer owner who wants feeder access, screened airflow, and bars that remain in place while open. Its 24-by-20-inch dimensions are the key fit boundary, so match them to the trailer opening.

View on AmazonWhy it ranks #2: Its 30-by-24-inch feeder format offers a larger opening, with drop-down aluminum bars and a screen door; the listing specifies no trim kit.
The 30-by-24-inch opening gives this RecPro feeder window more listed width and height than a compact feeder unit, while drop-down bars allow access for feeding, checking, and interacting. Its screen door supports ventilation while helping keep insects away, making it suited to horses needing an open-air trailer window.
Drop-down aluminum bars serve two functions: they help secure the horse during transport and lower for access to the window. The screen door lets air circulate while helping keep bugs away, so ventilation does not require leaving the opening entirely unprotected. Heavy-duty hinges are specified for repeated opening and closing. The listing notes no trim kit, so this is a better match when your installation plan already accounts for trim and the opening matches 30 by 24 inches.
- 30-by-24-inch feeder-window size
- Drop-down aluminum bars provide access and a barrier
- Screen door allows airflow while helping keep insects away
- Heavy-duty hinges are specified for repeated use
- No trim kit is included.
Skip it if you need a trim kit in the package; RecPro B07RSSGT35 lists one with its smaller 24-by-20-inch feeder window.
This suits horse-trailer owners prioritizing a larger feeder opening, ventilation, and convenient access behind bars. Check the 30-by-24-inch dimensions and plan for trim separately, since this listing specifies no trim kit.

#3 · Best Exit Option
3. HECASA Emergency Exit Window 30×20
- Material: Aluminium+Tempered Glass+Plastic+Rubber
- Material Type: Aluminium+Tempered Glass+Plastic+Rubber
- Compatible with Vehicle Type: RV
Best for: Measured emergency-exit replacement.
Why it ranks #3: The listing explicitly includes horse trailers, and this 30-by-20-inch emergency-exit window comes with a trim ring and screen.
A trim ring and screen arrive with this tinted HECASA emergency-exit window, making it a complete listed assembly for a range of trailer and RV applications. Its 30-by-20-inch nominal size is paired with specific inner and outer frame measurements, helping buyers compare the unit against an existing opening.
The nominal size is 30 inches wide by 20 inches high, but the stated inner frame is approximately 297⁄8 by 197⁄8 inches and the outside frame about 313⁄4 by 213⁄4 inches. Those measurements help distinguish the cutout fit from the exterior footprint when planning replacement work. Tempered glass, aluminum, plastic, and rubber make up the listed materials, while the included trim ring and screen support a finished, screened installation. Measure the actual opening before selection.
- Tinted emergency-exit window
- Trim ring and screen included
- Inner and outside frame dimensions are stated
- Listed for cargo trailers, horse trailers, campers, and teardrop RVs
- The stated 30-by-20-inch nominal size has a smaller inner frame and a larger outside footprint.
Skip it if you need a narrow vertical sliding window; NOVINO B0DTKM2CWW is listed at 12 by 22 inches.
Consider this HECASA when replacing a nominal 30-by-20-inch emergency-exit window in a horse trailer or other listed RV application. Its frame dimensions differ from nominal size, so verify the opening and clearance before installation.

4. Vintage Technologies Horizontal Window 30×20
- Material: Tempered Glass
- Material Type: Tempered Glass
Best for: Screened horizontal trailer pair.
Why it ranks #4: Designed for horse trailers as well as other trailer types, it has a half-vent with screen, tinted tempered glass, and a stated 301⁄4-by-20-inch cutout.
Two 30-by-20-inch horizontal-slide windows combine tinted tempered glass with a half-vent screen, giving horse-trailer owners screened airflow while limiting direct sun and visibility. The listing also specifies a trim kit for 1-1/2-inch wall thickness, making wall construction a central fit consideration for this pair.
The half-vent screen allows fresh air to enter while helping keep insects out, useful when a trailer needs ventilation without an uncovered opening. Tinted glass is described as providing privacy and minimizing sun-driven interior heating. A rust-free aluminum frame supports corrosion resistance and straightforward upkeep, while the neoprene seal around the inside frame is specified to require no sealant. The listing gives a 301⁄4-inch-wide by 20-inch cutout and a trim kit for 1-1/2-inch walls; verify those details before fitting.
- Two horizontal-slide windows included
- Half-vent screen supports airflow while keeping insects out
- Tinted tempered glass supports privacy and reduced sun heating
- Neoprene inner-frame seal specified with no sealant needed
- The included trim kit is specified for 1-1/2-inch wall thickness.
Skip it if you have a 12-by-22-inch vertical opening; NOVINO B0DTKM2CWW lists a paired vertical-window package with trim rings.
This pair suits horse-trailer owners wanting screened horizontal ventilation, tinted glass, and a stated sealant-free neoprene seal. Confirm the 30-by-20-inch cutout and 1-1/2-inch wall specification before choosing it.

#5 · Vertical Slider
5. Eapmic Vertical Sliding Window 24×20
- Material: Aluminum
- Material Type: Aluminum
- Compatible with Vehicle Type: RV
Best for: Vertical replacement for sheet metal.
Why it ranks #5: The listing names horse trailers among compatible uses and specifies a 24-by-20-inch replacement window with aluminum construction and tempered black glass.
A direct-replacement assembly with a vertical sliding layout makes this 24-by-20-inch Eapmic window an option for horse-trailer owners replacing an existing side window. The listing specifies an aluminum-alloy frame and tempered black glass, with fitment information for RV sheet-metal thicknesses of 2–6 mm or 48–55 mm.
The vertical sliding configuration suits installations where a tall side window is preferred over a horizontal slider. Aluminum alloy and tempered black glass are the listed materials, and the direct-replacement assembly approach can simplify the replacement workflow when the opening and wall construction match. The product information gives two sheet-metal thickness ranges—2–6 mm and 48–55 mm—so buyers should compare the trailer wall to those stated ranges. No components are listed as included, making package contents a consideration.
- 24-by-20-inch vertical sliding window
- Aluminum-alloy construction listed
- Tempered black glass listed
- Direct-replacement assembly described for specified sheet-metal thickness ranges
- No components are listed as included.
Skip it if you need trim and screen included; OUTPRIZE B0D6VLRGLD lists a trim ring and horizontal screened ventilation.
Choose this Eapmic for a horse-trailer owner replacing a vertical window whose wall matches one of the listed thickness ranges. The listing does not specify included components, so account for any installation parts your job requires.

#6 · Widest Opening
6. InSyoForeverEC Horizontal Window 42×12
- Material: Aluminum, Tempered Glass
- Material Type: Aluminum, Tempered Glass
- Compatible with Vehicle Type: Trailer , RV
Best for: Wide horizontal trailer opening.
Why it ranks #6: This horizontal slider is listed for trailers and RVs, with a 42-by-12-inch size, trim ring, screen, and reinforced lock.
At 42 by 12 inches, this InSyoForeverEC horizontal slider offers a wide, low-profile window format for a horse trailer or RV. Its aluminum-alloy and tempered-glass construction is paired with a reinforced lock and screen, supporting a combination of closed-window security and screened ventilation.
The horizontal sliding layout provides a broad opening without the tall profile of a vertical window. The reinforced lock is specified to enhance security when closed, while the screen helps prevent leaves and other debris from entering as the trailer is ventilated. A mounting trim ring, screw kit, and multilingual manual are included to support installation. The stated compatible metal-plate thicknesses are 2–6 mm or 48–55 mm, so check the trailer wall against those ranges before assembly.
- Large 42-by-12-inch horizontal format
- Reinforced lock specified for closed-window security
- Screen helps keep leaves and debris out
- Mounting trim ring, screw kit, and multilingual manual included
- The stated compatible metal-plate thickness is limited to 2–6 mm or 48–55 mm.
Skip it if you need a taller 30-by-20-inch horizontal window; Vintage Technologies B0CPTBGHT5 lists that size and a half-vent screen.
This fits owners seeking a wide horizontal window with a lock, screen, and listed mounting hardware. Its 42-by-12-inch proportions and specified wall-thickness ranges are important boundaries to check against the trailer opening.

7. OUTPRIZE Horizontal Window 24×20
- Material: Aluminum, Tempered Glass
- Material Type: Aluminum, Tempered Glass
- Compatible with Vehicle Type: RV
Best for: Half-vent horizontal replacement.
Why it ranks #7: Its 24-by-20-inch horizontal window has a tinted sliding design, a half-vent with screen, and a trim ring for two stated wall thicknesses.
A 24-by-20-inch horizontal slider with a screened half-vent gives this OUTPRIZE window a compact format for trailer owners seeking airflow and a movable screen. The listing includes a trim ring for 15/16-inch or 1-3/8-inch wall thickness, connecting the window choice to a defined installation range.
The horizontal half-vent provides screened ventilation, while the sliding and removable screen gives flexibility when cleaning or managing the screened opening. Aluminum and tempered glass are the listed materials, and the tinted glass adds the stated teardrop-window appearance. A trim ring is included for 15/16-inch or 1-3/8-inch wall thickness, so measuring the trailer wall helps establish whether the supplied ring suits the installation. The 24-by-20-inch dimensions also define the opening size to compare.
- 24-by-20-inch horizontal window
- Half-vent with screen for ventilation
- Sliding and removable screen
- Trim ring listed for 15/16-inch or 1-3/8-inch wall thickness
- The trim ring is specified for only 15/16-inch or 1-3/8-inch wall thickness.
Skip it if you need a 42-inch-wide window; InSyoForeverEC B0GXVGD4XT lists a 42-by-12-inch horizontal slider.
This OUTPRIZE window suits a buyer replacing a 24-by-20-inch horizontal unit who wants screened half-ventilation and a removable screen. Check the stated trim-ring wall options against the trailer before planning the installation.

8. HECASA Vertical Sliding Window 12×22
- Material: Glass, Steel
- Material Type: Glass, Steel
- Compatible with Vehicle Type: RV
Best for: Two vertical windows with trim.
Why it ranks #8: Listed for trailers and cargo campers, this 12-by-22-inch vertical slider includes two windows, trim kits, and mounting hardware.
Two 12-by-22-inch vertical sliding windows arrive with trim kits and mounting hardware, making this HECASA package suited to trailer owners replacing or adding a pair of narrow side windows. Tinted glass is specified for privacy and sun blocking, while the steel trim is described as rust-proof and durable.
The vertical sliding format suits narrow side openings, and the two-window package can address matching openings on a trailer. Tinted glass is described as blocking scorching sun and supporting privacy; the listing also says glass provides basic thermal and sound insulation. Steel trim has a powder-coated finish and is described as wear-resistant and rust-proof for daily use. Mounting hardware is included with both trim kits, so installation planning can account for the supplied parts and the 12-by-22-inch size.
- Two 12-by-22-inch vertical sliding windows included
- Tinted glass supports privacy and sun blocking
- Steel trim described as rust-proof and durable
- Trim kits and mounting hardware included
- The 12-by-22-inch vertical format may not match wider horizontal trailer openings.
Skip it if you need a wide horizontal opening; OUTPRIZE B0D6VLRGLD lists a 24-by-20-inch horizontal slider with a screened half-vent.
This HECASA pair fits trailer owners seeking two narrow vertical windows with tinted glass and included mounting hardware. Match the 12-by-22-inch format to the openings, since it will not serve a wider horizontal cutout.

9. NOVINO Vertical Sliding Window 12×22
- Material: Tempered Glass
- Material Type: Tempered Glass
- Compatible with Vehicle Type: RV, Travel Trailer
Best for: Vertical sliding retrofit pair.
Why it ranks #9: The listing targets cargo trailers and campers rather than horse trailers specifically; the package includes two windows, trim rings, and removable screens.
Two 12-by-22-inch vertical sliding windows, trim rings, removable screens, screws, and an installation drawing make this NOVINO listing a paired retrofit package. Tinted tempered glass and a mesh screen give cargo-trailer or camper owners a way to add or replace side windows while managing light and ventilation.
The vertical sliding format fits buyers seeking a tall, narrow side opening rather than a horizontal window. Tinted tempered glass is paired with a weather-resistant anodized aluminum frame, while the durable mesh screen supports screened ventilation. Two trim rings and two screw types are included, and the trim ring accommodates 15/16-inch or 1-3/8-inch wall thickness, with a stated 1/16-inch allowance. Butyl tape or other sealant is not included, so plan for that installation supply separately.
- Two vertical sliding windows included
- Tinted tempered glass and removable mesh screens
- Two trim rings, screw types, and installation drawing included
- Trim rings accommodate listed 15/16-inch or 1-3/8-inch wall thicknesses
- Butyl tape or other window sealant is not included.
Skip it if you want a horizontal window with a wider opening; Vintage Technologies B0CPTBGHT5 lists a 30-by-20-inch horizontal slider.
This pair suits trailer owners adding or replacing narrow vertical side windows who can use the included trim and hardware. Check the wall-thickness range and source sealant separately before starting installation.

10. LandCamp ProCamp Horizontal Window 36×15
- Material: Acrylic, Tempered Glass
- Material Type: Acrylic, Tempered Glass
- Compatible with Vehicle Type: RV, Tiny House, Teardrop Trailer
Best for: Precisely sized horizontal slider.
Why it ranks #10: This horizontal slider is described for RVs, tiny houses, and teardrop trailers, not horse trailers; its specified rough opening is 353⁄4 by 143⁄4 inches.
The LandCamp ProCamp window specifies a 353⁄4-by-143⁄4-inch rough opening and a 373⁄8-by-163⁄8-inch exterior footprint, giving buyers concrete dimensions for planning a horizontal-slider installation. Its listing also identifies a clamp ring and a 13⁄4-inch wall-thickness configuration, useful details when matching the window to a trailer wall.
The difference between the stated rough opening and exterior footprint helps distinguish the cutout from the frame coverage during installation planning. A clamp ring is included, and the stated 13⁄4-inch wall-thickness configuration provides a specific construction target for the assembly. The window is listed as a horizontal slider and uses acrylic and tempered glass. Its vehicle compatibility includes RVs, tiny houses, and teardrop trailers; horse-trailer buyers should rely on measured opening and wall details rather than the title alone.
- Exact 353⁄4-by-143⁄4-inch rough-opening dimensions stated
- Exterior frame footprint dimensions stated
- Horizontal slider format
- Clamp ring included with 13⁄4-inch wall-thickness configuration
- The specified rough opening is 353⁄4 by 143⁄4 inches, limiting fit to matching cutouts.
Skip it if your horse trailer has a 30-by-20-inch opening; Vintage Technologies B0CPTBGHT5 lists that horizontal-window size.
This LandCamp option suits buyers who can use its specific rough opening and 13⁄4-inch wall configuration in a horizontal-slider installation. Measure both cutout and wall before selection, since the listed dimensions define a particular fit.

View on AmazonAvoid a window-size mismatch
A window’s advertised size may not equal the opening you need to cut or replace, so verify the actual fit dimensions before choosing. HECASA Emergency Exit Window 30×20 states a nominal size of 30 by 20 inches, an inner frame around 297⁄8 by 197⁄8 inches, and an outside frame around 313⁄4 by 213⁄4 inches. Vintage Technologies Horizontal Window 30×20, by contrast, specifies a cutout of 301⁄4 by 20 inches.
LandCamp ProCamp Horizontal Window 36×15 gives a rough opening of 353⁄4 by 143⁄4 inches and an exterior footprint of 373⁄8 by 163⁄8 inches. These figures describe different parts of the window, not interchangeable measurements.
Measure the trailer opening and wall before ordering, and compare the maker’s stated rough opening or inner frame size with the matching measurement on your trailer.
Match the opening style to the job
Feeder windows, sliding windows, and emergency exits solve different horse-trailer needs, so choose by intended use rather than appearance alone. RecPro Horse Trailer Feeder Window 24×20 and RecPro Horse Trailer Feeder Window 30×24 are built around a feeder opening, with drop-down bars and screen doors. Their listed features support ventilation while keeping a barrier in place, but they are not described as emergency-exit windows.
HECASA Emergency Exit Window 30×20 is explicitly an emergency-exit model and includes a screen and trim ring; its opening style and purpose differ from the feeder models. Conventional sliders, including Vintage Technologies Horizontal Window 30×20, offer a half-vent with screen, while the vertical models slide in a different orientation.
Consider the horse’s access and airflow needs, the trailer’s existing opening, and whether emergency egress is a requirement before settling on a style.
How to Choose a Horse-Trailer Window
Window style and purpose
Choose a window style that matches how you want to ventilate or access the trailer. The RecPro feeder options use drop-down aluminum bars, and the 24-by-20-inch model also has a screen door attached inside; HECASA Emergency Exit Window 30×20 is specifically described as an emergency exit. Sliding alternatives include horizontal formats such as the 30-by-20-inch Vintage Technologies window and vertical formats such as the 12-by-22-inch HECASA.
Buyers who prioritize a feeder opening and a barrier while ventilating should look first at the RecPro models. Those replacing an existing sliding window should match its orientation and opening instead, while a buyer seeking an emergency-exit model should consider HECASA Emergency Exit Window 30×20.
Dimensions and wall compatibility
Match the window’s stated measurements to your trailer’s opening and wall thickness, rather than relying on a nominal size alone. Options range from the 12-by-22-inch vertical sliders to the 42-by-12-inch InSyoForeverEC horizontal slider. OUTPRIZE Horizontal Window 24×20 lists a trim ring for 15/16-inch or 13⁄8-inch wall thickness, while InSyoForeverEC Horizontal Window 42×12 specifies compatibility with metal plate thicknesses of 2–6 mm or 48–55 mm.
HECASA Emergency Exit Window 30×20 provides separate nominal, inner-frame, and outside-frame dimensions. Buyers replacing an existing opening should prioritize the matching cutout and wall range; buyers adding a window should use the specified rough-opening measurements and verify the trailer construction.
Included trim and ventilation parts
Check which installation and ventilation components are actually included, because packages differ across these options. RecPro Horse Trailer Feeder Window 24×20 includes a trim kit, while the 30-by-24-inch RecPro feeder model is explicitly listed without one. HECASA Emergency Exit Window 30×20 includes a trim ring and screen; the two NOVINO vertical windows come with trim rings and removable screens.
OUTPRIZE Horizontal Window 24×20 lists a trim ring and sliding or removable screen. LandCamp ProCamp Horizontal Window 36×15 includes a clamp ring, but its stated rough opening and wall-thickness fit should also match your installation.
Buyers wanting a feeder window ready with trim should favor the 24-by-20-inch RecPro; buyers sourcing a replacement should compare included rings and screens against the hardware their trailer already needs.
Which window suits my horse trailer?
For a dedicated feeder window with bars, a screen door, and a trim kit, choose RecPro Horse Trailer Feeder Window 24×20. If you need a larger feeder opening and can source trim separately, RecPro Horse Trailer Feeder Window 30×24 is the next fit. For an emergency-exit style, consider HECASA Emergency Exit Window 30×20 and check its inner-frame and outside-frame dimensions against your opening.
If you are replacing a horizontal slider, Vintage Technologies Horizontal Window 30×20 is explicitly listed for horse trailers and includes a half-vent screen. Eapmic Vertical Sliding Window 24×20 is another horse-trailer-listed replacement option.
Before ordering any model, confirm the trailer opening, wall thickness, and whether the listed package includes the trim and screen you need.
Frequently Asked Questions
How do I measure a horse-trailer window opening before ordering?
Measure the existing opening, not just the visible glass or frame. Check its width and height at several points, then compare those measurements with the product’s stated dimensions and installation requirements. Also verify the wall thickness and any inner- or outer-frame dimensions listed, since a mismatch can prevent a proper fit.
Do horse-trailer windows need a particular wall thickness or sealant?
Check the window’s stated wall-thickness range and compare it with your trailer wall before ordering; some listings specify a particular thickness. Confirm which trim or frame components are included, too. The supplied product information does not establish a universal sealant type, so follow the window maker’s installation instructions for sealing.
Should I choose a feeder window or a sliding window for ventilation?
Choose a feeder window if you want an opening designed for feeding and value features such as bars and an inside screen door. Choose a sliding window when you are replacing a horizontal or vertical slider or want that style of opening. Compare the opening dimensions and included screen or trim for either type.
What should I check about trim and screens before ordering?
Confirm the listing explicitly includes the trim kit or ring and screen you need; these vary by product. For example, the 24-by-20-inch RecPro feeder window includes a trim kit, while the 30-by-24-inch model does not. Check the package details before ordering, and plan to source missing trim separately if needed.
How do I check whether an emergency-exit window will fit?
Compare your trailer opening with both the inner-frame and outside-frame dimensions listed for the emergency-exit window, rather than relying on the nominal size alone. Also verify wall thickness and included trim requirements. The HECASA 30-by-20-inch model is an emergency-exit style, but its fit depends on your measured opening.
Final Words
For a dedicated feeder window, the RecPro 24-by-20-inch model is the leading fit: its drop-down bars, inside screen door, and included trim kit suit that use. Choose the 30-by-24-inch RecPro if you need a larger feeder opening and can source trim separately. For other replacements, match the opening and wall thickness to the listed dimensions, then verify whether the package includes the trim and screen you need.
