Install, Adjust, and Remove Classic SUP and Longboard Style Fins without Tools

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 recycled at the end of its 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 seize and will not damage your fin like a traditional bolt can.

The Finjak Tool-Free was initially designed with rear-tab fins in mind. For front-tabbed fins, the Finjak Tool-Free comes with an inherent safety 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 front or rear tabbed fin.
