Finjak, the easy tool-free way to install your center fin in a sliding fin box.
Made of hi-strength Acetal resin, the Finjak replaces the stock screw and sliding plate and eliminates the need for tools to install, remove, and adjust the position of your sliding box center fin.
The convenience of this fast, tool-free fin system allows easy stacking for transport (and less tear-through of board bags), but the greatest performance advantage of the tool-free Finjak is the ability to fine-tune your ride "Between sets---not Sessions!"
The Finjak works on front-tab fins but was designed 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.
