Window Block & Tackle Sash Balance 27-inch

See if our S380-27 or S385-27 match what you need. 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. You'll then have to choose a stamp option. Look for a stamp code on your old balance that designates this. If there is none or you are uncertain, obtain the exact weight of your window sash. You can then match that exact weight with one of the weight ranges listed alongside each stamp option on the balance product page.
