I have 6 extra Robin Casady stainless steel counterweight knobs that I am not using. They are brand new. If you would like to pick up a spare for your weights, or a set to upgrade any other weights that use a 3/8-16 thread then here you go. I actually dropped one once and it landed on the top and the resin shattered. That's how I learned that having extra's is a good idea. Asking $10 each and I will ship them out to your door.
I prefer Paypal.
