S385-27 27" Series 385 Channel Balance

I have non-tilt windows. The width of the channel balance is 1/2 inch. I have some 28" in length stamped B.S.I. 2730 and some 24" in lenght stamped B.S.I. 2330. See photos attached.

I need 6 of the 27" and 2 of the 23" there was no markings and I measured just the length of the metal. They did measure 9/16 which is your 1/2 ".

Channel is 27" long by 1/2" wide. Marking is "26 5 AX CMC 1"

Metal channel not including plastic end measures 27 inches. 9/16 wide.

Can you help me order the correct balances for two different windows? I have identified the two as SM and LG. I have additional photos, but I was limited to 5 photos.

Current balance has a 26D USB on them. Which part number do I need?

I need the right side sash balance complete metal piece with the roller end and plastic end along with the spring. It is 28" total in length.

MAKRINGS ON IT ARE 26-4 FM5 CMC 8: SPRING MEASSURES 11.5 " END TO END
