The Finjak Tool-free is the perfect fin bolt replacement that every longboard, midlength & retro board rider needs.
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.
