Best Topside Tool Boxes For Flatbed Trucks

#1 · Best Overall

1. Buyers Products 1701351

• Dimensions: 72"L x 13"W x 16"H
• Weight: 62 lb
• Material: Aluminum

Best for: Weather-sealed 72-inch storage.

Why it ranks #1: Its 72-inch, 0.100-inch aluminum build, dual flip-up doors, weather-sealing design, and included mounting hardware are a strong fit for flatbed storage.

A rain gutter paired with an automotive-grade bulb seal gives this 72-inch Buyers Products box a clear weather-protection focus. Its dual flip-up doors and .100-inch diamond-tread aluminum combine accessible storage with a corrosion-resistant shell that keeps the box positioned above the flatbed cargo floor.

The 72-by-13-by-16-inch cabinet uses dual flip-up doors, giving access at two points along the rail-mounted box. An integrated rain gutter channels water away, while the automotive-grade bulb seal helps keep tools dry and clean. The .100-inch diamond-tread aluminum provides corrosion resistance without unnecessary weight, and the 62-pound listed weight helps with handling plans. Included mounting hardware supports installation, while the topsider layout preserves usable space below for flatbed cargo.

Skip it if you need lower drawers for small-item sorting; the VEVOR 72-15-21 pairs its topsider compartment with two drawers.

This Buyers Products model suits flatbed users seeking two-door access and weather-sealed storage in a 72-inch cabinet. Its 13-inch width and 16-inch height remain important rail-clearance and installation considerations.

#2 · Longest Reach

2. Buyers Products 1721364

• Dimensions: 88"L x 16"W x 18"H
• Weight: 88 lb
• Material: Aluminum

Best for: Long dual-door weather protection.

Why it ranks #2: The 88-inch box offers dual flip-up doors, 0.100-inch aluminum, a rain gutter and bulb seal, plus mounting hardware and keys.

At 88 inches long, this Buyers Products box provides an extended rail-mounted cabinet with two flip-up doors and dual gas shocks. The shocks keep the doors open during access, while an integrated rain gutter and automotive-grade bulb seal help protect tools from water and debris.

The 88-by-16-by-18-inch cabinet spans a longer section of flatbed rail, and dual flip-up doors provide access at two points along its length. Dual gas shocks hold the doors open, freeing hands during loading, while the rain gutter and automotive-grade bulb seal direct water away from stored tools. Its .100-inch corrosion-resistant aluminum balances durability with lower weight than steel. Die-cast locking compression latches tighten the closure, and included mounting hardware supports installation.

Skip it if you have only 72 inches of rail available; the Buyers Products 1701351 offers a shorter dual-door cabinet.

This long Buyers Products model suits fleets and contractors needing two access points and weather-sealed storage across an extended flatbed rail. Measure for its 88-inch length and 16-inch width before planning installation.

#3 · Dual-Door Access

3. Buyers Products 1701551

• Dimensions: 72"L x 13"W x 16"H
• Weight: 69 lb
• Material: Aluminum

Best for: Dual-drop-door rail storage.

Why it ranks #3: This 72-inch, 0.100-inch aluminum box has two recessed drop doors and 8.6 cubic feet of stated capacity for broad tool access.

Two recessed drop doors give this 72-inch Buyers Products cabinet access along a .100-inch diamond-tread aluminum shell. The doors’ continuous hidden hinges help shield operating hardware from road spray and debris, while rail-top mounting keeps the storage above the bed floor.

The 72-by-13-by-16-inch cabinet offers 8.6 cubic feet of capacity, using space along the rails rather than the flatbed floor. Dual recessed drop doors make it possible to reach tools at separate points, while continuous hidden hinges help protect the hardware from moisture, dirt, and road spray. The .100-inch aluminum construction resists corrosion without the weight of a comparable steel box. Its 69-pound listed weight is useful to consider when arranging installation.

Skip it if you need drawers to divide small tools; the BeoneYuu Tw-72 includes bottom drawers and organizers in a 72-inch topsider.

This Buyers Products box fits crews wanting dual drop-door access and 8.6 cubic feet above the bed floor. Check that the flatbed rail can accommodate its 72-inch length and 13-inch width before installation.

#4 · Black Finish

4. Buyers Products 1721551

• Dimensions: 72"L x 13"W x 16"H
• Weight: 78 lb
• Material: Aluminum

Best for: Wide flatbed rail storage.

Why it ranks #4: Its 72-inch length, 0.100-inch aluminum, two recessed drop doors, and 8.67-cubic-foot capacity make it a substantial rail-mounted option.

Two recessed drop doors span this 72-inch Buyers Products topsider, giving crews access at separate points along a long cabinet. Its .100-inch diamond-tread aluminum construction pairs corrosion resistance with lower weight than steel, while the rail-mounted format keeps the box above the bed rather than occupying cargo-floor space.

The 72-by-13-by-16-inch footprint provides 8.67 cubic feet of storage while keeping the cabinet relatively narrow across the rail. Two recessed drop doors make it easier to reach tools from different positions along the box, and continuous hidden hinges with aircraft-grade support cables support repeated opening. Aluminum construction and a black powder-coated finish resist corrosion; rail mounting preserves space below for flatbed cargo. The listed 78-pound weight is relevant when planning installation.

Skip it if you need separate storage drawers; the VEVOR 72-15-21 adds two lower drawers beneath its topsider compartment.

Choose this Buyers Products box for work crews needing broad, lockable-access storage along a compatible flatbed rail. Its 72-inch length and 13-inch width define the space it occupies, so check the available rail area against those dimensions.

#5

5. UWS EC40052

• Weight: 45 lb
• Material: Aluminum

Best for: Wide dual-door tool access.

Why it ranks #5: The 72-inch double-door model mounts on bed rails and uses a welded 0.058-inch aluminum tub, aircraft cable supports, and a stainless steel locking system.

Two doors across a 72-inch cabinet let the UWS EC40052 provide separate access points along the truck bed rail. Its 9.4-cubic-foot capacity and rail-top mounting combine substantial storage with an arrangement that leaves the bed floor available for other cargo.

The 72-inch double-door configuration lets users approach tools from more than one position, helping organize access across the cabinet. UWS lists 9.4 cubic feet of capacity, while rail mounting preserves floor space for flatbed cargo. The one-piece tub is welded from 0.058-inch aluminum, which UWS describes as thicker than most aluminum tool boxes. Heavy-duty aircraft cable door supports and a stainless steel locking system support door operation and secure storage in work settings.

Skip it if you want a single opening on a 60-inch cabinet; the UWS EC40032 uses a single-door design and shorter length.

Choose the EC40052 when tools are spread across a long cabinet and two access points simplify retrieval. Its 72-inch length requires matching rail space, while the double-door format favors buyers who will use both openings.

#6 · Drawer Storage

6. VEVOR 72-Inch Contractor Box

• Dimensions: 72.05"L x 12.8"W x 21.06"H
• Weight: 92.6 lb
• Material: Aluminum, Stainless Steel

Best for: Drawer-organized contractor storage.

Why it ranks #6: Its 72-inch contractor format combines 0.07-inch aluminum with two lower drawers, though the listed dimensions and weight merit careful fit checks.

Two lower drawers distinguish this 72-inch VEVOR topsider, separating smaller items from the main compartment for a more organized contractor workflow. The 0.07-inch aluminum cabinet also lists a slim 12.8-inch width, so it adds layered storage while occupying a relatively narrow strip along a flatbed rail.

The upper compartment accommodates longer tools such as drills, cables, and crowbars, while two lower drawers provide separate layers for organizing smaller gear. At 72.05 inches long and 12.8 inches wide, the box offers broad storage without a deep bed footprint. Its 0.07-inch aluminum construction and solid welding support durability, and the included fixed rods and J-hooks provide installation hardware. A two-position latch offers a choice of latch position during access and closure.

Skip it if you prefer a lighter, simpler cabinet without drawers; the UWS EC40001 weighs 30 pounds and uses a single-door format.

This VEVOR fits contractors who want drawers alongside a long-tool compartment and can accommodate its 72-inch length. Its 92.6-pound listed weight is an important handling consideration during installation on a flatbed.

#7

7. BeoneYuu Contractor TopSider

• Dimensions: 72"L x 13.5"W x 21"H
• Material: Aluminum

Best for: Deep storage with lower drawers.

Why it ranks #7: This 72-inch aluminum box adds two lower drawers, organizers, folding stainless steel locks, and a rubber seal for buyers prioritizing separated storage.

Deep, tall compartments paired with bottom drawers and organizers give the BeoneYuu 72-inch TopSider multiple ways to separate tools. Its 21-inch height provides a taller cabinet profile than shallow topsiders, while a complete rubber seal and stainless steel folding locks add weather and security provisions.

The 72-by-13.5-by-21-inch cabinet combines deep, tall storage spaces with bottom drawers and organizers, letting buyers separate different tool types instead of relying on one open area. Its aluminum construction keeps the box in the topsider category, and the rubber seal is specified for added protection against weather and dust. Stainless steel folding locks provide the listed security feature. The 21-inch height is a key fit consideration where the flatbed rail area has limited vertical clearance.

Skip it if you need a lower-profile cabinet; the Buyers Products 1701351 measures 16 inches high and offers dual flip-up doors.

Consider this BeoneYuu for crews who value drawers, organizers, and tall storage in one 72-inch box. Its 21-inch height and 13.5-inch width should suit the available flatbed rail space before choosing it.

#8

8. UWS EC40032

• Dimensions: 13.63"W x 17"H
• Weight: 38 lb
• Material: Aluminum

Best for: Single-door cargo-conscious storage.

Why it ranks #8: The 60-inch black box has a welded 0.058-inch aluminum tub, aircraft cable door supports, and a stainless steel locking system.

A one-piece, welded 0.058-inch aluminum tub gives this 60-inch UWS topsider a substantial shell while keeping tools above the bed rail. That mounting position leaves the truck bed available for other cargo, making this single-door model a practical option when rail storage matters more than access from multiple openings.

The 60-inch single-door layout concentrates access in one opening, a straightforward arrangement for stowing a set of frequently used tools together. Its welded, one-piece tub uses 0.058-inch aluminum, which UWS identifies as thicker than most aluminum tool boxes for strength. Mounted atop the bed rail, it adds storage without taking up the bed floor. The stainless steel locking system and heavy-duty aircraft cable door supports address security and supported door operation during loading.

Skip it if you want two separate openings across a longer cabinet; the UWS EC40052 provides double-door access over 72 inches.

This UWS suits buyers who want a 60-inch rail-mounted cabinet with a single opening and a welded aluminum tub. It is best where one access point works for the stored tools and the bed floor needs to remain clear.

#9

9. UWS TBTS-60

• Weight: 14.5 lb
• Material: Aluminum

Best for: One-hand single-door access.

Why it ranks #9: This 60-inch rail-mount box includes a MicroSeal gasket, lockable T-handle, and stainless steel aircraft cables, but is identified for LTL shipping only.

A lockable T-handle and 90-degree-opening door make this UWS 60-inch topsider accessible with one hand. Its 0.058-inch one-piece aluminum tub mounts atop the bed rail, leaving the truck bed floor available while providing 7.8 cubic feet for tools and cargo.

The single door opens 90 degrees, giving a wide loading path, and stainless steel aircraft cables support it during use. A lockable T-handle enables one-hand access, while the MicroSeal gasket helps seal out moisture and dust. The 0.058-inch one-piece aluminum tub provides 7.8 cubic feet of storage and mounts on the bed rail to preserve floor space. Its 60-inch length makes it a fit for buyers with a matching stretch of rail.

Skip it if you need two access points along a 72-inch cabinet; the UWS EC40052 offers double doors and 9.4 cubic feet.

This UWS works for buyers who prioritize one-hand access, a wide-opening door, and rail-mounted storage. Its single-door, 60-inch format suits a defined tool set and available rail span rather than multi-opening access.

#10

10. UWS EC40001

• Dimensions: 48"L x 13.63"W x 17"H
• Weight: 30 lb
• Material: Aluminum

Best for: Compact 48-inch rail storage.

Why it ranks #10: At 48 inches long and 30 pounds, this rail-mounted single-door option is the shortest listed box, with a welded 0.058-inch aluminum tub.

At 48 inches long, this UWS single-door topsider takes a shorter stretch of bed rail than the larger listed cabinets. Its rail-top mounting leaves the cargo floor open, while the welded 0.058-inch aluminum tub provides a one-piece enclosure for tools in a compact footprint.

The 48-by-13.63-by-17-inch dimensions make this the shorter UWS option in the supplied group, useful when a longer cabinet would occupy too much rail space. Its single door keeps access simple, while the one-piece tub is welded from 0.058-inch aluminum, which UWS describes as thicker than most aluminum tool boxes. Rail mounting preserves the floor for cargo, and the listed 30-pound weight helps buyers account for the box during handling and installation.

Skip it if you need more cabinet length; the UWS EC40032 extends to 60 inches while retaining a single-door topside layout.

Pick this model when your flatbed offers limited rail length or you prefer a 48-inch cabinet. Its single door and compact dimensions suit tools that fit within the shorter enclosure, rather than long-item storage needs.
