Heavy-Duty Aluminum Diamond Plate Construction
The Under Bed Tool Box is constructed from aluminum diamond plate—a strategic material choice that delivers professional strength while minimizing weight and providing superior corrosion resistance. At 103 pounds, the aluminum construction keeps the unit manageable during installation while providing the robust durability necessary for equipment mounted beneath trucks exposed to road debris, weather, chemicals, and demanding conditions.
Aluminum diamond plate offers multiple advantages for underbed storage applications: natural corrosion resistance ensures long-term durability even when exposed to road salt, moisture, and harsh environments; lightweight construction minimizes impact on vehicle weight and fuel economy compared to steel alternatives; diamond plate texture provides structural rigidity and distinctive professional appearance; and the material withstands years of exposure to road conditions without rusting or deteriorating. The aluminum door and hinge specifically reduce weight while protecting against corrosion in these high-wear, high-exposure areas.
The clear ARMOR TUF powder coat finish over aluminum diamond plate preserves and enhances the material's distinctive appearance while providing additional protection. This commercial-grade clear coating resists scratches, chips, and UV damage while allowing the aluminum diamond plate pattern to remain fully visible—creating the classic professional appearance that defines quality commercial vehicles. The clear finish maintains the bright aluminum appearance, showcases the diamond plate texture, protects against oxidation and weathering, and creates the traditional look preferred by many professional operators.
The heavy-duty welded construction with C-channel reinforced lid ensures structural integrity even when subjected to vibration, impacts from road debris, and the stresses of daily professional use in challenging environments.
Comprehensive Weather Protection and Security
The Under Bed Tool Box is engineered with multiple systems working together to protect contents from weather and theft. The rain gutter and full weather seal keep moisture out of the tool box and away from your equipment—critical for underbed storage exposed to road spray, rain, snow, and washing. The memory-resistant D-shaped ribbed weather strip maintains sealing effectiveness through thousands of opening and closing cycles and extreme temperature variations.
The stainless steel D-handles are easy to grip even with gloves on and create a tight door seal when latched. The rotary style, two-position latch helps protect against theft and weather by providing secure closure. The heavy-duty three-point latching system on the underbody truck tool box means valuable supplies will be safe and protected—three separate locking points distribute force across the door and make prying entry extremely difficult.
Security features can be keyed alike on request for fleet operations managing multiple vehicles with underbed storage—allowing one key to access all units across your fleet for simplified key management.
Versatile Access and Installation Features
The door opening measures 13.5" high by 55.25" wide, providing excellent access to the 11.2 cubic foot interior. This substantial opening allows you to load and retrieve larger items, reach across the full width of the box, and organize contents efficiently. The tool-less quick release doors adjust from 90 degrees to 180 degrees with QuickClips and no tools required—allowing you to position doors for optimal access in different situations or vehicle configurations without carrying tools.
The compact size underbed design (approximately 60" long, 18" wide, 18" high) fits beneath heavy-duty trucks, semi trucks, flatbed bodies, platform bodies, and dump truck bodies. The 18" height and width are sized to fit within typical frame rail spacing and ground clearance constraints while maximizing storage volume. The 60" length provides substantial storage capacity without excessive length that could interfere with fuel tanks, exhaust systems, or other undercarriage components.
Installation takes approximately 1 hour and involves mounting the unit securely to the truck frame or body using appropriate hardware. Note that mounting hardware is not included—this allows you to select fasteners appropriate for your specific truck frame configuration and mounting location. Professional installation is recommended to ensure proper positioning, secure mounting, and clearance verification.
Key Features

Professional Applications and Capacity
The Under Bed Tool Box is specifically designed for applications where truck bed space must remain completely available for primary operations. This underbed storage solution is ideal for flatbed trucks carrying materials or equipment that require full bed access, dump trucks where bed space is operational workspace, platform trucks hauling oversized loads, semi trucks needing secure storage without sacrificing trailer space, contractor trucks carrying lumber, pipe, or materials in the bed, utility trucks with service bodies needing supplemental storage, or any operation where adding storage capacity without consuming bed space creates significant operational advantages.
The 11.2 cubic foot capacity accommodates chains, binders, straps, tarps, hand tools, power tools, jumper cables, recovery equipment, safety gear, spare parts, fluids, or any items you need to transport securely but access occasionally. The underbed location keeps these items secure, organized, and out of the way while preserving your entire truck bed for revenue-generating cargo and equipment.
The aluminum construction and weather sealing make this suitable for equipment that must withstand road spray, weather exposure, and harsh conditions. The secure three-point latching protects valuable tools and equipment from theft—particularly important for underbed storage that's somewhat less visible than bed-mounted boxes but still accessible to potential thieves.
The clear-coated aluminum diamond plate finish is particularly popular among owner-operators and fleet managers who prefer the traditional professional appearance of visible diamond plate—a look that communicates quality, durability, and professional standards in commercial trucking.
