FinJak

The FinJak is a revolutionary piece of equipment that allows you to adjust the position of your fin in any Fins Unlimited center fin box without the need for a plate and screw, allowing surfers to adjust their fin positioning while in the water!

Want a looser feel? Just move the fin forward. Want it stiffened up? Move the fin towards the back of the box and click the FinJak into position and you're good to go!

Come in a variety of colors.
