William Optics Mortar Piers and Pier Head Adapters

William Optics Mortar pier head adapters connect a mount to the William Optics Mortar pier, so the same pier can carry different mounts. Each adapter is made for one mounting interface.

Versions are available for iOptron mounts, for Vixen-style bases and for Takahashi mounts, plus a 3/8" screw mount adapter for heads and bases that use a standard 3/8" thread. Choose the one that matches the base of your mount or tracker.
