Need 4 new spring assemblies

Question

As I was trying to say, my spring assembly looks like your 350 series, but is stamped 1520, and the metal body measures 16 inches in length. I need 4 of these for two bathroom windows. See picture. Would like to chat with someone about this as soon as possible. Thanks, Don

Hello,

It's tough to be sure based on your photo, but your balance appears to have non-winged top and bottom fittings, while the S350 has a winged bottom fitting. I'd suggest taking a look at our S351-16, with a 15-002 bottom attachment, or S390-16, 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 1520 spring strength option for your replacement balances. Thank you!
