The SP Tools USA 53” Off-Road Series Truck Box features a heavy-duty steel frame and fully welded 17-gauge construction to withstand the daily grind of work trucks and rugged job sites. Four deep lockable drawers glide on sealed roller bearings rated for 155 lbs., giving smooth access to tools even when loaded with heavy gear. Waterproof rubber seals keep equipment dry and protected, even in inclement weather. Steel feet allow for easy forklift handling or bolt-down installation in the truck bed, while stainless steel carry handles make repositioning simple.
