Robin Casady Weights 2 21.7 lbs., LNIB. I bought these and then change mounts and never used them. These stainless steel counterweights fit the 1.875" shaft of the Williams GT-1HD mount and the Astro-Physics 900 and 1200 mounts. Each weight has rounded edges, a bronze bushing, and a non-rotating brass plunger to prevent scaring of the counterweight shaft. The brass plunger is spring-loaded so it retracts when you loosen the thumbscrew. 3" long x 6" dia. for 1.875" dia. shaft.
