Window Channel

Thanks for reaching out! You have the S770-34 Channel Balance, with a 34D stamp. To determine if this replacement can be installed as is, you'll need to double check that your balances install using a screw, at the top of the window track.

The shoe is likely to be either the 15-167 or the 15-179. You'll need to remove the existing shoe and compare each of their dimensions (shown on the website) to confirm the correct replacement match.
