Specs & Features

The Finjak Tool-Free surfboard fin installation device replaces the metal plate and screw of your single fin longboard, midlength, 2+1 surfboard or SUP and allows instant adjustment by hand.

Made of acetal plastic resin for strength and lightness the Finjak Tool-Free can be recyled at the end of it's life. Unlike a fin bolt and plate Finjak Tool-Free is a 'one-piece clamp' which is both easier to locate in your finbox and also less likely to be lost. Finjak Tool-Free will not rust or sieze and will not damage your fin like a traditional bolt can.

The Finjak Tool-Free was intially designed with rear-tab fins in mind. For front-tabbed fins the Finjak Tool-Free comes with an inherent safetly feature. If you hit something in the water it may release. This reduces impact damage to both fin and fin box and potentially expensive repairs to your surfboard. Should you hit something with your board or fin it's good practice to check the security of your fin regardless of using a fron or rear tabbed fins.

Surfers Say

I think you saved my finbox this past weekend. Rode in a little too long. Fin was front tab. Hit the sand hard and felt it jam, then release. Figured I was screwed. But the fin popped and the finjak was still in the fin box. Popped the fin back in and walked to the car as though nothing had happened.
