Thanks for writing in. See either our S390-28 or S351-28. The only difference between these two balances is the 'depth' of the bottom nylon shoe. Compare both with your old hardware to see what matches best. You will need to select a stamp option. Look for a stamp code on your balance's metal channel. if there is none or if you are uncertain, weigh your window sash. You can then match that exact weight with one of the weight ranges listed alongside each stamp option on the product page.
