Pro Box Fin Systems

Fiberglass Supply

Finally, a fin system that addresses many of the shortcomings of existing systems in the surfboard marketplace. Here is a system that is easy to install and easy to adjust. Adjustments can be made to the fin position forward and backward and the cant [fin angle]. These adjustments allow the performance of a surfboard to be tuned to the conditions, type of surfboard or rider. The fin cant is adjusted through a revolutionary patented insert mechanism that provides controlled angles, initially 4 different inserts are provided 0°, 4°, 6°, and 8°, but more in the future!

A single reusable jig is used to handle the alignment, routing, and anchoring of the box during the installation process. No fin is required to install the box as the jig correctly locates the box on the board while suspending it over the routed hole. These jigs are extremely inexpensive and reusable!

The design of the system makes it simple to accommodate custom fiberglass fins as there are no angles in the base! Features a simple solid base that is easy to manufacture and strong. A V-notch in the base provides a platform for the screws to land on, when tightened this creates a compression fit of the fin and insert into the box. Plug fin tabs fit in our box, so you can keep your existing fins and use them!

Discover the hidden potential of your boards, by experimenting with your fins, try ProBox!
