The Finjak Tool-Free fin installation device replaces the plate and screw of your single fin surfboard, making it easy to install, remove, or adjust your fin in seconds.
Made of hi-strength Acetal resin a finjak is a 'one-piece quick release clamp' that allows you to find the perfect sweet spot for harmonising your board and fin setup while still in the water - in seconds!
The next generation replacement for fin bolt and screw systems which retrofits all of your tabbed surfboard fins. No more rusted bolts, lost plates - no screwdrivers or fin keys.... Finjak is a quick-release system that simply slides into your finbox and 'clicks' shut making for hassle free fin adjustments in the water between waves.
**The Finjak works on front-tab fins, but I designed it for rear tab fins. If you’re using it on a front tab fin and you hit something in the water, it could release, especially on longer fins. This can be a good thing, saving a broken fin or box, (or person). It's a good practice to check your board whenever you hit something, but especially important when using a front-tab fin.
