Mounting SUP Fin
US-Box Snap-In Fin
Important: Place the red rubber nubs so that they fit into the recess when inserting the fin. Then push the inserted fin backwards.
(ULTRALIGHT SUP, TEAM, STORMRIDER)
Important: The screw only so far turn in that it touches the fin or comes to a standstill in the hole and thus blocks the fin. (approx. one rotation 360°)
If the screw is screwed in to the point of resistance and more, this can damage the thread.
