Jordan, 2430F
Hello,
It looks like you have either our S351-25, with a 15-002 bottom attachment, or S390-25, with a 15-001 bottom attachment. Take a look at the image below to determine which balance you'll need. You'll also need 2430 spring strength options for your balances.
Choose the spring strength option based on the stamp on your balance.
Good morning -
There are quite a few top sash guides that are compatible with the Series 390 balance. As you said, you'll need to remove yours to identify it. It mostly comes down to style and dimensions. Feel free to send us a photo of yours if you need a hand!
Thanks! It looks like your dimensions match up well with our 18-199. Give it a look to be sure you agree.
You are very welcome. Here at Swisco, we work as a team to make sure you get the best service possible. We are glad to hear that everything has worked out for you. Please think of us again on your next project.
