FCS II Fin Plugs (Sold individually)

Note – If ordering an individual rail plug, please leave a note in the comment section to let us know if you need the left or right plug

FCS II Fin Plugs are for use with all new FCS II fins, however they will also fit the older-style FCS two-tab surfboard fins.

The FCS II plug system requires no grub screws. It is an efficient key-less system for fin installation and release. It is therefore easy to insert and remove fins in just a matter of seconds. As a result, you can adapt your surfboard to the conditions on the day with no hassle.

The fin plugs have a recessed leading edge which gives a flush base connection. Consequently this improves water flow.

FCS II plugs give a solid connection between fin and surfboard. Equally there is a seamless transition between the fin and board surface.

The construction of the fin plug uses a corrosion resistant titanium tension rod and a rotating, wear-resistant polymer barrel. When the surfboard fin is inserted into the fin plug, the barrel interacts with a groove detail in the fin to lock it into place creating a secure fit.

Testing has been done on the FCS II Fin System (over 4,000 cycles of installing & then removing the fin). The FCS II system should outlast the board in normal conditions.
