Astro-Physics Brass Pin for Counterweights
This is a brass pin for securing Astro Physics counterweights- working with a knob inside the weight to fasten and secure it to the shaft. This is just the pin, but when used with the proper knob and the counterweights themselves, the pin slides through the counterweight then secures the shaft and weight together as you tighten the knob. It's far simpler than it sounds, and in essence this part is meant as a replacement in case your counterweight set should become damaged and the pin need replacing.
