Part Number

Question

My balances do not appear to have a stamped number present. How do I determine the correct replacement? The home was built in 1995. The window is vinyl, single hung.

Your pivot shoe appears to be a match our 15-191, which is designed to work with the 1/2" thick Series 160. I believe these parts will work for you, but you need to read the stamp printed on the band of the original spring to determine the proper weight option.
