Putco's Pop Up Lockers have the look of conventional Locker Rails but offer the convenience of tie downs. These handy pop up tie downs have four tie down locations to handle any type of truck cargo. Made from NeveRust Stainless Steel, they're able to secure loads up to 500 pounds. Installation is easy using the existing stake pockets so there is no need to drill. Best of all, they're backed by the Putco limited lifetime warranty.
