The Wooden Camera UVF Extension XL attaches to the optional UVF Mount v2 to extend the position of your monitor or viewfinder by an additional 7.5". A clamping knuckle allows for positioning on the UVF Mount's NATO rail, while a socket cap can be loosened to adjust tilt of the extension rail. Safety pins at the end of the rail prevent accidental removal of your mounted device. While designed for use with the UVF Mount v2, the Extension XL can attach directly to any standard NATO rail.
