FCS Fin Key

The FCS Fin Key is your go-to tool for fins, leashes, and more. The steel key is compatible with a range of FCS-related products, making it a one-stop shop for adjusting gear throughout your day. The FCS Fin Key is specifically made for inserting and removing FCS fins but is compatible with set screws on other items such as cuffs and rail savers on surf and SUP leashes. Weighing only 9 grams,  you can easily clip the fin key onto a keychain or tuck it in the pocket of your beach shorts.

FCS stands for Fin Control System. Founded in Queensland, Australia in the early 1990s, FCS is the most successful, widely used surfboard fin system in the world.
