I dropped one of the knobs on my Robin Casady weights and chipped off the corner. Learning from this I now have 6 extra black Robin Casady knobs that I don't need. If you have one of his weights (or several) and would like an extra knob I am selling these $10 a piece shipped to your door. These will also fit anything that uses a 3/8-16 thread about 1" long.
These are not a product I offer on my website but simply some extra's that I bought online and don't need. As such, I am passing them on to others.
I prefer Paypal
