Window Balance

Hi Dzung,

Thanks for posting! Your channel balances appear to be either the Series 380 with a 1" shoe depth or the Series 385 with a 1-3/32" shoe depth. To confirm which series you have, carefully compare the dimensions shown on the diagram below. There is a chance the shoes could measure 7/8", if so, please let me know as your balances would need to be a custom assembly.

Once you've confirmed the series, you'll need to select the stamp for your respective balances. For the two 13" balances, you'll need the 1220 and 1230 stamp options; the 16" balances will need the 1520 stamp option.
