Channel balancer

Can you identify this part? I purchase a channel balancer from you be fore for the same house. Looks like same kind of window from the outside but larger. That order worked well.

Hi there!

With this combination of attachments, you could have either an S380 or S385 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. You'll also need to remove and weigh your sash to choose the appropriate spring strength option. There's a chart on the S380 and S385's product page that will show you which option you'll need based on the weight of your sash. 

If you have any further questions just let us know.
