sash window spring assembly

Question

I need two window sash spring assemblies. Details in pics, 28" long for the metal part. Need channel balance shoe sets as well. Let me know the exact parts list and total and estimated delivery date.

Thanks a bunch.

Hi Bill. This looks like either an S380-28 or S385-28. The only difference between these two balances is the 'depth' of the bottom nylon shoe, so compare both with your old hardware to see what matches best. Look for a stamp code on the metal channel that indicates what stamp option you need. If there is none or you are uncertain, weigh your window sash. You can then match that exact weight with one of the weight ranges listed alongside each stamp option on the product page.
