Hi,
Trying to figure out what the proper replacement channels are for two different sized windows I have.
On both, the measurements of the metal are 1 inch longer than what is in the marking (26 vs 27) & (29 vs 30)

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 2640 strength options for the 27" balances and 2950 options for the 30" balances.
Thank you and let us know if you have any other questions or concerns.
