Hello,
I have 14 year old windows made by Kinco. Single-hung, non-tilt, 1/2 inch channel width. I took out the window, and it weighs 28 pounds. The balancers have a block and tackle system that the string goes through. Channel balance is 35 inches long (metal part only - plastic ends not counted)... I have no idea which series of balances to look at on your website. Your system maxed out the number of pics I could send. Could you please help?
Thank you,
Dave

Hello, With this combination of attachments, you could have either an S380-35 or S385-35 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 3440 spring strength options for your replacement balances to support a window sash between 23 and 30 lbs. Thank you and let us know if you have any other questions or concerns. Comparison of the S380 and S385 balance shoes.
