16" Sash Balance

Question

Greetings,

Im having a very difficult time finding this particular Sash Balance here in my town. I figured you may shed some light and give me lead on this. The metal channel is 16" long x 9/16" deep. Spine of channel is 1/2" wide, but on the open side of channel its 5/8" wide from rolled edge to rolled edge- exterior dimension.

Thanks,
Noe

Hello,

It looks like you have either 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 1540 spring strength option for your replacement balances. Thank you!
