replacing window balance

Question

Hello. I'm trying to replace window balance and think this is a 380 series. Last time I tried to narrow it down, I thought there were two options with bottom shoes which were almost the same size. The bottom shoe wings seem to be 8-9/16th of an inch.

The channel is 15" long. Both the top and bottom shoes have wings. There is an ink stamp which says "4 9 26# LO CALDWELL". Thanks for your help.

With this combination of attachments, you could have either an S380-15 or S385-15 channel balance. You’ll need to measure as shown below. The Series 380 has a 1" bottom attachment, and the Series 385 has a 1-3/32" attachment. You'll also need to weigh your sash to determine which option you'll need. There is a chart on the product page that explains how to choose your option based on the sash weight.
