LokBox micro fin box - White.
The LokBox fin system uses a tapered cavity and matching fin base, providing a very solid attachment from fin to board. Lokbox can be installed on the foam blank, or after laminating.
In addition, the largest benefit of the the Lokbox fin system is the box allows̴ adjustability of the fin 1/2"̴ forward and backwards. This system is popular with twin-fin or quad set-ups, as this small adjustment allows the surfer to tune in a "looser" or "tighter" feel.
