window winged top and bottom balance for single hung 12in window. Window weight 9lb

Hi Daniel,

Thanks for posting! Your balances are either the S380-12 with a 1" shoe or the S385-12 with a 1-3/32" shoe. To determine which series is needed for your window, look over the dimensions from the diagram below to confirm the depth of your bottom shoe.

You'll need to select the 1130 stamp option.

Comparison of the S378, S380 and S385 balance shoes.

For instructions on removing/installing these balances, take a look at the video tutorial below.
