Looking to find all of the parts pictured. Unfortunately I do not have both coil springs or any information on the weight they are. The window size is 37.5x26" if that helps to get an idea of size and weight.
Thank you!

Thanks for writing in. This looks like our 15-111 Pivot Shoe. This shoe uses either our Series 160 or Series 165 Coil Springs, depending on the thickness of your old coil springs. I'm afraid we can't tell the weight of your window sash that from that information alone. If you could get the exact weight on a bathroom scale, we can work out the coil balances you need. Many thanks.

The weight of the sash is 23lbs. The thickness of the coil springs look to be 1/2" thick.

15-111 looks perfect! Thank you!!!

Thanks for getting back to me. If your coil springs are 1/2" thick then you need our Series 160 springs. If your window sash weighs 23 lbs, then I would use (4) of our S160-5 springs, with a pair on each side of the window sash. These springs support 5.5 lbs of weight individually, so having a pair of these on each side of the sash would total 22 lbs of support. With Coil Balances, being within 1 lb of the exact window sash weight is fine. Let me know if you have any other questions.
