Window balance numbers 28c

Take a look at both our S380-29 and S385-29 channel balances. You will need to measure the depth of your bottom shoe, like in the diagram below, and compare it to each of the bottom shoe fittings of both balances. That will determine which balance will work. You want to make sure that you are using a balance that is not damaged to make the most accurate recommendation.
