I have attached a number of photos to identify my balance springs. it appears in need a few of these. there are no numbers on the spring anywhere. the metal is 1/2 inch and the length is 36'. the window is aluminum and weighs 16 lbs.

I can not find any identification on the window.

This is a weird one. I'm not sure if we have any top attachment that matches yours. Could you reuse it? Theoretically, you could just use a Series 351 channel balance, then drill out the default 19-002 top and install your old one. See the video below for more information on attaching nylon attachments to a channel balance.

The top pieces are all broke. The pic of the one i sent you was taped together. I am going to assume the series 351 will work, but before I order them. Here are a few more pic to review.
Your the man, thanks for the help.

Ah, I see. I'm not sure if our Series 351 can work, honestly. Your top nylon attachment is just far too different, and we haven't been able to find anything that even remotely comes close. I am sorry we cannot offer a better replacement.
