Channel Balances - 3 different sizes

Question

Three different window sizes. Each needs 2 channels.
1. 28" long stamped 27 4 D BSI
2. 30" long stamped 29 9 PG BSI
3. 26" long stamped 25 9 PG BSI

My guess is that I need the 380 series. 1/2" width. The winged shoe would be 15-005. My measurement of the depth of the shoe is 1".

Pictures attached. All CB's have same measurements except for lengths. CB's 2 & 3 are for large and heavy windows.

Please let me know what I need and order will be made.

Hello,

As long as the bottom fitting measures 1" deep, you would need the S380 channel balance. The 28" balances would need 2740 strength options. Your other two lengths have stamps from an old weight system that is no longer used, so you would need to weigh your sash to determine which option you'll need. There is a chart on the product page that explains how to choose your option based on the sash weight. Thanks for posting!
