Buying help

How do I know which fin box I need?

Check the board, existing fin system and fin type. FCS, Futures and single-fin boxes are not interchangeable.

Can I replace damaged fin boxes?

Often yes, but the repair needs correct routing, reinforcement and resin choice.

What about leash plugs?

Leash plugs are separate parts. Choose by board construction and repair or build requirements.

Should I buy fins at the same time?

Only after the box system is confirmed.

If you are replacing a damaged box, inspect surrounding glass and foam before assuming only the plug needs replacement.
