The Spring-Loaded Center Fin Retainer is a fast, reliable solution for securing your longboard center fin without the need for a fin key. Designed for standard center sliding fin boxes, this tool-free fin fastener uses spring tension to hold your fin firmly in place while allowing quick adjustments in the water or on the beach.

Perfect for longboarders, noseriders, and travel surfers, the spring-loaded mechanism prevents loosening, reduces fin movement, and eliminates lost screws. Built from corrosion-resistant materials, it’s ideal for everyday surf conditions.

Whether you’re dialing in fin placement between sessions or locking it down before a long paddle, this fin retainer delivers secure hold with instant adjustability.
