Stainless Steel Counterweights

These stainless steel counterweights fit a 1.125" shaft.

Each weight has rounded edges, a brass bushing, and a non-rotating brass plunger to prevent scarring of the counterweight shaft. The brass plunger has a stainless steel spring so it retracts when you loosen the thumbscrew. On other companies' weights the plunger falls into the bore. and prevents it from going on the shaft - unless the knob is down.

Do not over-tighten screws. Too much force can cause brass plunger to mushroom.
