The UVF Mount (Rod/NATO Rail) from Wooden Camera enables you to attach a viewfinder on your rig, and it is a version of the UVF Mount v2 without the 15mm Tube Clamp portion or Sled. This kit is ideal for the NATO Handle (Plus) which has an integrated 15mm clamp. The kit would typically be used with the UVF v2 Sled or RED Spinner Mount. A safety pin prevents accidental removal. UVF v2 Sled can attach directly to any NATO-style rail.
