Channel Balance

Question

I have a channel balance that says 1990 FX 30 on it.  It's 20" long and 1/2" wide.  Any idea what part I need to order to replace it?

Hello,

With this combination of attachments, you could have either an S380-20 or S385-20 channel balance. You need to measure as shown below. The Series 380 has a 1" bottom attachment, and the Series 385 has a 1-3/32" attachment. You'll also need to weigh your sash to determine which option you'll need since your stamp is part of an outdated weight system. There is a chart on the product page that explains how to choose your option based on the sash weight.

Thank you and let us know if you have any other questions or concerns.
