Balance for Insulate Window

Hello there!

I recommend our S380-24 or S385-24 channel balance based on what you show here. The best match ultimately depends on the depth of your bottom shoe. The Series 380 has a 1" deep shoe, and the Series 385 has a 1-3/32" deep shoe. Measure as shown in the image below to see which one matches best. You will also need the 2330 strength option.
