FCS - Leash Cup
The FCS Leash Cup is a molded plastic cup with a stainless steel pin and capped off design. The plug is made to be installed under the fiberglass saving a step and add strength. Just drill the hole directly into your shaped blank, resin the plug in, glass over it, and sand off the cover. If needed this plug can be installed like a traditional leash cup after the board has been glassed.
