Hello,
I was wondering if you could help me with determining what replacement parts I would need for my window. Please see attached pictures. My understanding is that I need an 11" block and tackle part, but I wasn't sure if I needed an exact match when it came to the stamp code (1090). Could I get away with a 1020 or 1040? I estimate the window weighs about 40 lbs but I can check. Any help is greatly appreciated!
Thank you,
Mike

Hi, Mike!
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 to remove and weigh your sash to choose the appropriate spring strength option. There's a chart on the S380 and S385's product page that shows you which option you'll need based on the weight of your sash.
If you have any further questions just let us know.
