A pair of 2230 channel balances

Question

Hello. Need a pair of channel balances for a single hung aluminum window (older models I think). Window is likely over 20 years old.
The size of the aluminum balance is 23" (not including plastic tips).

Can you help me figure out which ones I need? Thanks

Hello,

It looks like you have either our S351-23, with a 15-002 bottom attachment, or S390-23, 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 2230 spring strength option for your replacement balances. Thank you!
