Channel balancer

Hello!

With this combination of attachments, you could have either an S380-30 or S385-30 channel balance. You’ll need to measure as shown below. The Series 380 has a 1" bottom attachment, and the Series 385 has a 1-3/32" attachment. If your sash weighs 29 pounds, you'll need the 2950 stamp option, which supports a sash weighing 28 to 32 lbs.

If you have any questions just let us know!
