Installation Diagram
This kit combines our standard 12" pier top plate with our 8" adapter for Orion Atlas/Celestron CGEM type mounts. The Atlas/CGEM adapter mounts to the 12" plate with shoulder bolts from underneath. The Atlas/CGEM adapter is also compatible with other Atlas clones that use a center bolt with M12 threads. See our compatibility list below. The 8" Atlas/CGEM Adapter kit may also be purchased separately.

This combination may also be purchased with our 3/4" stainless steel anchor bolt kit.
