Fin Box Longboards

The universal fin box system for fin box base fins with pins such as Longboard and SUP fins. Easy to install after the board has been glassed using one straight line with a router.

TIP: When installing your fin box make sure to stuff the boxes cavity/interior with a strong piece of cardboard or a dummy fin so that when the resin around the box is gelling it doesn't bow the fin box due to the thermal heat reaction created during the catalyzing process.
