This kit allows you to replace the quick-release clamp on the Sidemount Wimberley Head (WH-200-S) with the swinging arm and platform of the full gimbal Wimberley Head (WH-200). The Head can easily be converted back to the Sidemount version when desired by reversing the steps. The procedure is simple, and the only tool required is a 5/32 hex key (Included in kit).
