Window Balances

Thanks for writing in. See our S390-31 or S351-31. The only difference between these two balances is the 'depth' of the bottom nylon shoe, so compare both with your old hardware to see what matches best. If you can't read the stamp code on your balance's metal channel, you'll need to weigh your window sash. Match the exact weight of the sash with one of the weight ranges listed alongside each stamp option on the product page.
