SWISCO - The Replacement Hardware Authority

Double hung blance

A home owner from Brighton, CO says:
I need to replace a balance that is stamped "26 4 FT CMC 4".

I think I need a 26" 380 series. Does that seem correct? Does the old code tell the weight I need?

Thanks, Pete

Tom from SWISCO responded:
I'm afraid not. The stamp only indicates how strong the spring is. Keep in mind that the Series 380 comes with the 19-005 top and 15-005 bottom. Carefully compare the pictures and dimensions we show for these pieces to your own hardware to confirm if they match.
