This cab guard install kit allows you to adapt a cross over tool box to your Westcan cab guard or complete truck rack. This kit will work on cross over tool boxes up to 72″ wide on full size trucks and 68″ on compact trucks. The crossover kit is all aluminum construction and comes complete with no drill stake pocket inserts and non corrosive hardware to ensure that you will never see rust on the rack or your truck. When using rail caps, cutting of the tie rail is required for proper fit. Stake pocket inserts are only available on trucks that have stake pockets.
