Help Identifying window balance

Question

Hello,

I believe this is part S380-26 option 2520 I just want to be sure. The measured channel length is 26'' and the width is 1/2''. Also it has 2520 stamped on the channel as well.

Thank you for any help you can provide.

Thanks for writing in. I agree, this looks a lot like the S380-26 or S385-26. The only difference between these two balances is the 'depth' of the bottom nylon shoe; if you haven't already, compare both with your old hardware to confirm what matches best. In either case, you are right: you will need a stamp option of 2520.
