This is made of all plastic with a small pin for the wheels to run on. It is a very poorly designed piece. If at all possible, something similar but better built would be helpful. If not, I can try what you might find. Depending on price, I need roughly 15-20 pieces. I can send a photo of the actual part too, if needed.

This actually looks better than what I have. So I need some Sash Balancers and will order a couple of these to see if they work, then get what I need if they do work. Thank you for your help. Order is coming.
