Thanks

Thank you. We do not seem to have a standard option that can support that sash weight. Your balance will have to be custom made. I'm going to email you a purchase link and price quote for your review. You can use this to place an order on our website.
As for the clip in your picture, are you referring to the Pivot Shoe, or the metal tab that fits into the pivot shoe? If it's the pivot shoe, look at our 15-178, or even our 15-129 and compare them to your own hardware to see what matches. If it's the small metal clip, see our 15-043.
