SWISCO - The Replacement Hardware Authority

side window sash

A quick learner from california says:
I have a Marque window with the following stamped on the balance; "31 4 EW CMC 10". The length is 32 inches and it looks like the guides are different than any you show. I have posted two photos of the top and bottom guides and want to know if you can provide two replacement balances?

Hey, thanks for posting. I've narrowed this down to two possible channel balance Series: either our Series 380 or our Series 385 balances.

Now, as you can see, there is only one difference between these two Series, and that is their bottom shoe. The Series 380 uses the 15-005 while the Series 385 uses the 15-004. I can't quite tell what you have based on your pictures, though. Please carefully compare their dimensions to your own hardware and see which is a better match.
15-004 and 15-005
