Surfboard Fin Systems & Plugs

Shop surfboard fin systems and plugs for board building, fin box installation and repairs. The range includes FCS, Futures, leash plugs, fin boxes, dummy fins, longboard boxes and installation parts.

Start by matching the fin system and the job: new install, repair, replacement, leash plug or single-fin box. Accuracy matters because plug placement affects strength, alignment and fin fit.

Buying help

Are FCS and Futures interchangeable?

No. FCS and Futures systems use different boxes and fins. Match the board and fin system before buying plugs or boxes.

What are dummy fins for?

Dummy fins help hold alignment during installation or repair so boxes cure in the correct position.

Can I install plugs myself?

Experienced builders can, but placement, routing, resin choice and reinforcement matter. Ask for advice if unsure.

Do leash plugs use the same parts?

No. Leash plugs are separate hardware and should be matched to the board and repair or build job.

Fin box work is precision work. Confirm system, angle and placement before routing or glassing.
