Mountable to any flat surface, including Front Runner drawer systems and pickup truck beds. The slide-out extension gives you an additional 460mm/18'' x 330mm/13'' work surface. Mounting holes are predrilled. High-strength bearing drawer slides allow the tray to extend nearly 100% from the anchored base. The unique design keeps the slide rattle-free when closed. A latching arm securely locks the drawer in the closed position. Features a hold open mechanism to prevent the slider from closing when the vehicle is parked on uneven surfaces. Finished in the same durable weather-resistant black powder coating as the Front Runner Slimline II Roof Rack. Can have many other uses, like carrying tools, boxes, or other adventure gear. Four (4) STRA063 are included to secure your fridge to the fridge slide. Mounting hardware included for wood and metal surfaces.
