Replace Channel Balance

Question

I am looking to replace the channel balances on our windows and need help identifying what to order. We measured 22" and see there is a marking for a 2136 on the old balance.

This looks like an S351-22 or S390-22. The only difference between these two balances is the nylon shoe depth, so compare both with your old hardware to see what matches best. You'll have to choose a stamp option. That stamp code looks possibly like 2130 to me, which would support a window sash in the weight range of 12 through 15 lbs. Let me know if that is right or if you have any other questions.
