Large Poly Triangle Trailer Box

The DEE ZEE Large Poly Triangle Trailer Box (Model DZ 91717P) is a heavy-duty storage solution engineered for vehicle-mounted cargo organization and field equipment transport. Constructed from impact-resistant polyethylene, this triangular tool box delivers reliable weather-sealed storage in a compact profile that mounts securely to trailers, trucks, and work vehicles without compromising aerodynamics or visibility. The 36-inch length combined with 24-inch width and 20-inch height creates usable internal volume for tools, gear, tactical equipment, and supplies while the poly construction resists rust, corrosion, and damage from harsh outdoor environments.

Specifications deliver practical field functionality: the box measures 24 x 20 x 36 inches with a lightweight 25-pound footprint, allowing for easy installation and minimal payload impact on towing capacity. The black polyethylene construction sheds mud, salt spray, and chemical exposure without degradation—critical for users operating in corrosive environments. Triangular geometry maximizes internal capacity while reducing wind resistance during highway transit, a design consideration for personnel carriers and multi-agency transport vehicles. The poly material requires no maintenance, sealing, or protective coatings to maintain integrity across seasonal temperature swings.

This trailer box suits field teams, off-road operators, emergency response units, and outdoor professionals who need secure, weather-protected equipment staging between operations. Law enforcement support units, search and rescue teams, and tactical training groups deploy this type of storage for portable range equipment, recovery gear, and field supplies. The sealed compartment protects sensitive equipment from dust, moisture, and UV exposure while the poly material withstands impacts from loading/unloading cycles in remote or austere locations where administrative storage is unavailable.

Trailer-mounted tool boxes occupy a distinct category between underseat storage and full-size cargo boxes—offering accessibility without permanent vehicle modification. The DZ 91717P positions itself as a mid-capacity option for users requiring organized compartmentalization without the weight penalty of steel construction. DEE ZEE's poly lineups have established market presence in fleet and municipal applications where corrosion resistance and low maintenance outweigh premium material costs.
