Please see photos of existing window balance, including of both ends, metal clip, nylon fittings, underside, and stamps/markings. The length of the channel portion measures 35 inches. The markings on the channel state: 34 5 EX CMC 7

Thank you.

Hello, thank you for posting! 

It looks like you have either our S351-35, with a 15-002 bottom attachment, or S390-35, with a 15-001 bottom attachment. Take a look at the image below to determine which balance you'll need. You will need a 3450 stamp option. Please let me know if you have any questions.
