These Mounting Post Adapters are most commonly fastened to an end of our P-Series Posts as a mounting platform for our Opto-Mechanics as pictured below. These four adapters offer every combination of 1/4"-20 (M6) and #8-32 (M4) tapped holes and counterbores, assuring compatibility across a wide range of optical mounts.

      This example illustrates a KM100 mounted to an MA4 and fastened to a P-Series post. All capscrews are easily accessible to attach/remove items as required.
