Window balances

Hey Kenny. This appears to be either our S351-29 or S390-29. The only difference between these two balances is the depth of the bottom nylon shoe, or 'heel-to-toe' measurement, so compare both with your old hardware to see what matches best. To know what stamp option to select, obtain the exact weight of the window sash. You can then match that exact weight with one of the weight ranges listed alongside each stamp option on the shop page.
