Hello,
I have several channel balances that need to be replaced. All the windows are of the same non-tilt design. The balance that I have is 30" long and stamped with 29 4 DT CMC 4. Attached are the pictures of the bottom and the top. Thank you very much,
Vladimir

Thanks for your post! I'm confident we can supply the replacement for this window balance. Although, to narrow down the correct match, I'll need to see a photo of the metal piece connecting the spring and cord (string) in the middle/center of the balance.

Please let me know if you have any questions.

Thanks for the additional photos. This window balance is a match for either the S380-30 or the S385-30. You'll need to confirm the depth of your shoe to confirm the right series.

Our 2940 stamp should work in place of the one you have but it would be a good idea to double check that the sash weight falls between 23 to 28lbs.

Comparison of the S378, S380 and S385 balance shoes.
