Question

Could you help me identify this channel for a single hung window from CGI
It seems to be a Series 4100, but I don't have the original sticker anymore
Channel size: 29"

Thank you

Thanks for posting. It looks to me you have either the S378-29, S380-29 or S385-29 Channel Balance. The only difference between these three balances is the 'depth' of the bottom nylon shoe. See below. Measure your old balance's shoe depth to see what matches best. For a stamp option choose 2850.

Comparison of the S378, S380 and S385 balance shoes.
