The Claw Accessory allows you to take your existing Mob Mount and convert it into a Mob Mount Claw with two small screws. With a few twists of the knob, you can open the Claw Accessory from 1/4" all the way up to 2" to fit anything from handlebars to odd shaped tubes and grab handles. Included in the accessory pack are two fasteners and a 1/16th hex wrench to secure the attachment bracket to your Mob Mount Switch Cradle.
