Probox Fin Systems
Probox Fin Systems is a relatively new fin system brought to market by a longtime player in the surfboard fin market. Probox Fins boasts a robust fin box that allows the shaper and user wide latitude in determining fin placement and angles. Probox utilizes a set of inserts that allows the fin angle to be changed and for fore and aft adjustment of the placement of the fin in the box, regulating the amount of water flow between the fins.
Probox Fins box is a universal box that accepts Probox Fins and FCS fins without modifications. Other manufacturer's fins will also fit with some modification to the base of the fin.
Probox Fins install easily and quickly with a low cost jig system and a flush trim router bit that are included in the inexpensive installation kit. You provide the router (preferably a trim router).
