FCS X-2 Fin Plug (Please note a normal dual tab fin will need 2 plugs and some keels will need 3 plugs)
The FCS1 Dual Tab plug is so far the most commonly used fins plug system in the world. They are easy to repair as supposed to other fin systems, and the FCS H-pattern adds strength by effectively anchoring the plugs into the surfboard.
Please note most fins will need 2 of these plugs per fin.
Thruster set up: 4 x Rail plugs and 2 x Centre plugs.
