Monterey Windows Single Hung balancers

Question

Hi there,

I am looking to replace balances in Monterey Windows, single hung.
they have the number 2720 B.S.I 0
and the other one reads 2120R B.S.I
Do you have any of these or replacement ones?

Hello,

It looks like you have either our S351, with a 15-002 bottom attachment, or S390, 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 2720 strength options for the larger balances, which should have 28" long metal channels. The shorter balances will have 2120 options for 22" balance channels. Take a look and let us know if you need anything else. Thank you!
