Buyers Products 1702305 Black Steel Underbody Truck Tool Box

The 1702305 model from Buyers Products is built for demanding environments with heavy-duty steel construction and weather resistance. The box uses 14 gauge black steel with a corrosion-resistant powder coat to withstand harsh job sites and exposure to the elements. A secure locking system combines a stainless steel compression latch with a recessed drop door, delivering strong theft deterrence and moisture protection for tools stored in the truck bed. An all-weather design features a continuous hidden hinge, a replaceable gasket system, and aircraft-grade cables to seal out dust, dirt, and road debris for reliable underbody toolbox performance.
Intended for underbody mounting, this 18 x 18 x 36 inch model prioritizes security and durability. Its steel construction resists impact and weathering, while the locking system helps prevent unauthorized access. The combination of a hidden hinge and replaceable gasket reduces maintenance needs and helps maintain a dry interior after rain or road spray. This box suits contractors and fleet operators seeking a robust, USA-made option for vehicle storage and organization.
Buyers Products 1702310 Black Steel Underbody Truck Box with T-Handle Latch

The 1702310 model advances the same underbody concept with a taller 48-inch length, enabling greater storage capacity while maintaining steel integrity. Like the 36-inch variant, it uses rugged 14-gauge black steel and a corrosion-resistant powder coat for long-lasting wear in tough environments. The lock system is a stainless steel compression latch paired with a recessed drop door to deter theft and protect contents from moisture. The addition of continuous hinges and a durable gasket system helps seal out dust, dirt, and weather, making it suitable for exposed truck beds and open-air work zones.
For fleets that require more space without sacrificing security, this box provides a practical balance between size and protection. The reinforced structure helps resist heavy loads and rough handling, while the weather seals aim to minimize maintenance and cleaning needs after job site exposure. It’s well-suited for builders, technicians, and landscape crews who need reliable, secure storage on long jobs or daily drives.
Buyers Products 1702303 Black Steel Underbody Truck Box

The 1702303 box offers an 18 x 18 x 30 inch footprint, providing a compact yet sturdy storage solution for tools and materials. It shares the same heavy-duty steel construction, powder-coated finish, and secure lock system as its larger siblings. The recessed drop door, stainless steel compression latch, and continuous hinge contribute to a weather-tight interior that guards against dust and moisture intrusion. This size is ideal for smaller work vehicles, service vans, or trucks with limited bed height, where maximizing space is critical.
Users can rely on the robust build to withstand rough weather and frequent daily use. The tool box’s integration with a truck bed edge design means minimal installation complexity, while the secure latch helps keep tools safe when the vehicle is parked in busy job yards or urban sites. This model appeals to electricians, plumbers, and specialists who value a compact, secure, and durable storage option.
Garvee 36 Inch Black Steel Truck Bed Tool Box

The Garvee 36-inch option offers a commercial-grade steel build with 12-gauge steel and a textured black powder coating, ensuring resilience in extreme heat or cold. It emphasizes quick-access storage through a no-lock, easy-grab design, which is ideal for contractors who need fast tool retrieval during projects or tailgate events. The lid is supported by a steel pneumatic hinge that opens smoothly to about 110 degrees, providing a controlled and safe closing action to minimize injuries caused by sudden lid movement. While it focuses on expediency, the solid construction still provides dependable protection against the elements when locked or secured as needed.
This model is well-suited for users who prioritize rapid tool access and straightforward operation on busy sites. It can serve as a reliable main or secondary toolbox for construction crews, landscapers, or maintenance teams who frequently add or remove gear from their truck bed. For those who require a balance between durability and convenience, Garvee’s offering presents a practical option with a lighter, simpler approach to toolbox design.
VEVOR Steel Trailer Tongue Box

The VEVOR tongue box is a 36 x 12 x 12 inch steel storage chest designed to fit a pickup truck bed, RV, or trailer tongue. It ships with a lock and keys, emphasizing theft deterrence alongside weather resistance. The construction emphasizes rust and wear resistance through a double-sided dusting process, and the fully welded seam construction protects interior contents from leaks. A weather-sealing strip and overlapping door design further shield tools from rain and snow, ensuring dry storage regardless of the weather. The box aims at versatility for trucks, trailers, or RV setups, making it a reasonable choice for multi-vehicle households or contractors with varied equipment needs.
Users may value the combination of a secure lock, solid steel body, and practical dimensions that accommodate a wide range of tools and accessories. The VEVOR option can be part of a broader security strategy for a fleet or personal vehicle, offering a durable storage solution that resists corrosion while providing straightforward access when needed. It’s particularly suitable for outdoor work environments where weather exposure is common and tool protection is essential.
Buying Guide
Key considerations when selecting steel tool boxes for trucks include material thickness, mounting compatibility, and sealing performance. Steel gauge (e.g., 12-14 ga) directly influences strength and weight. Underbody designs can offer better security and storage efficiency, but may require specific mounting hardware or vehicle compatibility checks. A locking mechanism—such as a stainless steel compression latch or T-handle latch—enhances theft resistance, while a recessed drop door helps resist moisture intrusion. Look for weather seals, continuous hinges, and replaceable gaskets to extend interior life and reduce maintenance.
- Size and storage needs: Choose dimensions that fit your truck bed, tailgate area, and typical tool inventory. Larger boxes increase capacity but may affect weight distribution and fuel economy.
- Security: Evaluate lock quality, anti-corrosion finishes, and whether the design resists prying and moisture. Consider whether you need a lockable lid or a quick-access design.
- Weather resistance: Seals, gaskets, and hinged designs should be able to shed water and dust. Underbody styles often provide extra protection against spray and mud.
- Installation: Confirm compatibility with your truck’s model year and bed type. Some boxes attach directly to frame rails or bed sides; others are underbody with hidden mounting hardware.
- Maintenance: Powder-coated finishes and gasket systems determine how easy it is to clean and maintain the box over time. Replacing gaskets can extend life in harsh climates.
- Cost vs. value: Heavier-duty boxes typically cost more upfront but offer longer service life in demanding environments. Factor in lock quality, weather sealing, and warranty terms.
Overall, steel underbody and trailer tongue boxes provide robust protection, security, and weather resistance for tools and equipment. When selecting among options, consider how you use your truck most often, your typical climate, and whether you need extra storage capacity or quicker access. The right choice should balance durability, security, and practicality to fit your specific work routine.
