Parmount window balancers

Thanks for reaching out to us. The balance in your photos looks similar to our S765-27. Look this product over and let me know what you think, or if you had any questions. I'd be happy to assist you with anything you wanted to know about this assembly.

I think I see what you mean. Now that you mention it that clip is a little different. I wonder if yours is an older design.

Can you show me where it attaches? That might give me a better idea of how it works and whether the modern Series 765 can still replace it or if adjustments need to be made after all.
