NOTE: DO NOT ORDER THIS FOR A STANDARD BODYBOARD. THEY WILL NOT WORK. SEARCH FOR THE SHACKLE LEASH PLUG IF YOU HAVE A BOARD OTHER THAN THE CUSTOM X BEAST! These are the plugs needed to install a leash on the Custom X Beast, or a very thick soft top surfboard. These leash plugs are extra thick and extra strong for the boards that are over 3 thick. They work with any leash we carry.
