Need to replace block / tackle channel balance for vinyl single hung tilt window

A home owner from USA says:
Good morning! First, your site is very helpful! Great design, clean looking!

I had problem with your form submission. This is a new discussion.

I need to replace block / tackle channel balance for vinyl single hung tilt window. Has 325r stamped on it plus BSI. It is 33 inches (w/o lock attachment). It is spring type. Pics attached. Believe it is called side install. If it helps, windows are 9 years old. Can you determine which of your replacements I need from pics? [] It looks very similar to your Series 795-33.

Thank you! I'm glad you like our site. As for your balance, I think our S795-33 channel balance is a great match. The only thing that's a little odd is the stamp. I think our 33D may be the corresponding option, but you may want to weigh your sash to confirm. Two balances with the 33D option can carry a sash weight of 25 through 30 pounds.
