Short Strap Mount Kit
The 509 Short Strap Mount Kit for Altitude 2.0 Helmet allows the user to securely attach any 509 Goggle Short Strap Kit to 509 Altitude 2.0 Helmet with the threaded accessory mounts (nutserts) on either side of the helmet. This replaces the 'stick on' method that is supplied with all short strap kits.
