Highway Products' truck bed slide-out cargo tray (Model XT-4000) can support a load of up to 4,000 pounds. The marine-grade aluminum tray is designed to slide cargo out of the truck bed quickly. The roller coaster of the tray uses sealed roller bearings to glide onto the galvanized steel Tee-Bone track system. Once inside the truck, the system safely locks into position using the sual Stab Lock locking mechanism that allows users to lock the tray in 10-inch increments. The roller coaster standard and custom slides are designed to fit all brand and bed-size truck, vans, and service bodies. Each slide comes with an installation kit, instructions, and a lifetime warranty.
