To complete the setup for your Elevate Rack, this is where you will find the finishing touches. If you already have your rails, you may want to consider the tie- down set. The cleats will fit in your t- slot rails to help keep your cargo stable when you are on the move. Want to keep your channel clean? Take a look at the channel guard which comes in a roll of 188 inches. This will help keep dirt & debris from accumulating in the t- slot channels. For just a few extra dollars, you can both enhance the use of your Elevate Rack- and protect it at the same time!
