This Northcore FCS Fin Key is compatible with all FCS grub systems.
The Northcore FCS Fin Key is used for surfboard fin removal and installation from your board. If your board has an FCS adjustable fin set up, you need one of these for sure.
Compatible with all FCS gear, in particular the stainless steel grub screws you find in the fin plugs of surfboards.
It’s an essential bit of kit for every surfer, stand up paddle boarder and kiteboarder to have in their gear bag.
Many a time have we lost these at the beach, in the car, or loaned them to a friend “temporarily”! It’s worth having some as spare in your gear bag.
