Window balance.

Question

Hello. I hope you can help with this I believe this is from the series 395 Chanel balance. The number stamp in the balance is 3020. Also will need that top guide the part that goes attached to the window sash to retain the balance.

Hello,

It doesn't look like your top or bottom fittings have wings, which means that you could have either our S351-31, with a 15-002 bottom attachment, or S390-31, with a 15-001 bottom attachment. Take a look at the image below to determine which balance you'll need. You'll also need a 3020 spring strength option for your replacement balances.

As for your top sash guide, I would recommend starting by comparing the dimensions shown on the 18-110 product page to yours. Thank you!
