BIC Surfboard Thruster Fins 10.5cm

A set of 3 x 10.5cm thruster fins designed to be used with older model BIC surfboards where the fins screw in from the deck of the surfboard. Not compatible with FCS fitting fin plugs. 

Includes:

3 x 10.5cm Fins

3 x allen bolts

3 x Plastic Washer

3 x Metal Washer

1 x allen key.

Instructions:

Turn your surfboard upside down so that the fin boxes are facing up. Find the fin that is coved (rounded) on each edge. This is your center fin. Push the fin firmly into the fin block so that it points towards the back of the board. Repeat with the other two fins making sure that the rounded edge of the fin is closest to the rail of the board. See diagram included. Once all three fins are secure in the board, turn the board over. Get your washers and bolts ready. The metal washer goes onto the bolt first, followed by the plastic washer. Align the bolt and washers through the board with the fin and screw in securely using the allen key provided. Repeat with the other two fins and check they are secure.
