Installation Diagram
This kit combines our standard 12" pier top plate with our 8" adapter for the Orion Sirius EQ-G mount. The Sirius adapter mounts to the 12" plate with shoulder bolts from underneath. The Sirius adapter is also compatible with other Sirius EQ-G clones that use a center bolt with M10 threads. See our compatibility list below. The 8" Sirius Adapter kit may also be purchased separately.

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