Window channel balance

I can't tell without measuring, but depending on the depth of your bottom shoe, you need Series 380 or Series 385 channel balances. You can use Series 380 if your shoe is 1" deep and Series 385 if your shoe is 1-3/32" deep. Measure your metal channels to choose a balance length, and weigh your window sash to confirm the weight option. Every balance has a product description on our site. The product description contains a chart that tells you which weight option to choose, based on the weight of your window sash. That will provide you all the information needed to order.
