Mounting rings attach to your mounting plate and hold your tube assembly firmly in place.
The tops of the rings are flat which allows you to support your guidescope, camera or other accessories. The rings feature a hinged assembly with thumbscrew closure. They are felt-lined to prevent marring of your tube. Please order the size that corresponds to the outside diameter of your tube assembly.
