  • Astro-Physics Machined Safety Stop Knob

    Use this finely machined, anodized one-piece safety stop knob to decorate the 1.875" counterweight shaft of the Mach1GTO.

The AP Safety Stop Knob is also suitable for the 1.125" counterweight shaft of all 400, 600 and 800 mounts. It sports a 5/16-18 thread. Astro-Physics Product Number: MSSKB
