WIndow Balances

Question

Hello,

I need 4 each of both balances shown. 4 x 28" and 4 X 33".

The 28" balances have a stamp of 27 3 BSI
The 33" balances have a stamp of 32 5 bx cmc 11

I believe the parts on both are the same.

Hello,

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 3250 spring strength options for your 33" balances and 2730 for the 28" replacement balances.

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