Chinook FinFast Mtg System

A solution to the hassle of attaching a U.S.-base fin to your windsurf, surf or SUP board. The FinFast is an innovative design that allows the fin nut to always remain connected to the fin for faster and easier fin installation and removal — and no more lost parts. The key is the narrow parallelogram shaped plastic nut that rotates perpendicular to the box when tightened for a secure fit, and then parallel to the box when loosened for fast removal.Pack of 2.
