Window Channel Balances needed

For your balances, have a look at our S380-16, S385-16, S385-28, and S380-28. These look almost identical in appearance, with the exception of the 'depth' measurement of the bottom balance shoe. You will need to measure the 'depth' measurement of your bottom balance shoe, the way it is shown in the diagram below, to determine which of the two balances will work. Whichever one chosen for the 16" will use a 1520 option and whichever one chosen for the 28" balance, will use a 2730 option.
