The Tmat Cargo Management System is designed to fit standard truck beds ranging from 6 ft. 6 in. to 6 ft. 9 in. in length. When fully assembled, it measures up to 6 ft. 6 in. long x 4 ft. 2 in. wide and fits conveniently between the wheel wells of most full-size truck beds. This design allows the mat to be easily placed or removed without hassle. Built for flexibility, the system can be customized to suit your specific hauling needs. The included blockers insert directly into the mat, letting you create a layout that keeps tools, equipment, and gear securely in place. By minimizing shifting during transport, the Tmat helps keep your cargo organized and protected on the road. Fits 6' full-size trucks including long bed F150 & 1500 (RAM, Chevy, GMC), standard bed 250/350 & 2500/3500, Toyota Tundra long bed, and others. WARNING: Tmat is designed for enclosed and covered cargo areas such as covered truck beds, SUVs, vans, campers, and enclosed trailers. Extra precautions must be taken when used in an open-air cargo area to protect from wind and roll-overs. Tmat should never be used in an open-sided bed or with the tailgate down.Comes with the following components: 12"x12" Panels (x24), 12"x2" Strips (x18), Tight Fit Blockers (x4), Adjustable Blockers (x2), 50" Ramp Kit (x1)
