The Putco Stainless Steel Locker Side Rails with polished finish help to carry tough loads and add a custom look to your vehicle. Made from die-cast, durable NeveRust stainless steel tubings of 1-3/4 inch diameter with a full-coverage O-ring gasket that protects against erosion, these locker rails have 1000 pound vertical and 1200 pound horizontal tie-down strength per side. The side rails are sold in pairs, easily install in minutes via stake pockets and require no drilling or cutting (some drilling may be required for trucks without stake pockets). This product is backed by Putco's NeveRust lifetime warranty.
