The sleek blow-molded sliding track design is multi-functional and weatherproof. First, you can store your rods on the wall in a vertical position. If you want to modify the rack to fit your needs, remove the deep cavernous rod handle caps to mount rods in a horizontal position. The innovative "J" hooks are specially designed with a flexible tab to ensure your rods remain securely in place. The top and bottom tracks have removable end caps so other 3 in 1 all-weather rod racks can be added to expand rod storage capacity from 8 to 16 or even 24. If you like to store your rods with alternating tips and handles for maximum capacity, remove the end caps slide out the J clips and the rod handle holders then reset them tip to handle.
