The Putco Pop-Up Mirror Chrome Finish Tie-Downs are sold in pairs (2 per set) and provide a tie-down strength of 600 pounds per kit. The design of the patent-pending cam system makes the post of the tie-down "pop" up when pushed; pushing down on the post again returns it to its hidden, down position. Installation is easy via stake pockets and requires no drilling. These tie-downs are made of NeveRust stainless steel with 3 millimeter OEM-quality chrome plating and are backed by the Putco NeveRust lifetime warranty. They are universally designed to fit full-size domestic pickup trucks only and work well with or without bed caps.
