The injection molded fins are designed to break off in the event of collision to minimize board damage and injury to the surfer.
[2] The FCS system was designed by Brian A. Whitty in Elanora, Australia, and patented on November 7, 1995.
The plug design and use of set screws enables the fin to be easily removed and installed for storage or travel.
These plugs can be installed in a variety of different ways in order to create the correct degree of strength needed for the fin to function.
Adding two grub screws and a small silicon insert allows you to secure your two tab fins into the new system.
