No more missing screw and plate for fin mounting! No tools needed with FinJack. Screw and plate are so 10years ago!
Bill Bahne introduced his Fins Unlimited box in 1971, and the Bahne-based removable/ adjustable fin system remains the standard for classic single-fin and 2+1 equipped surfboards and stand-up paddle boards.
The convenience of a 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 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.”
