Channel balance order

Question

I need two channel balances of the kind shown in the photos with a 30 inch rail and 4 with a 27 inch rail. There are no identification marks on them. I do not know sash weight ( they are at a rental but could go over and weigh sashes if necessary. Let me know thanks Mitch

Hello,

It looks like you have either our S351, with a 15-002 bottom attachment, or S390, with a 15-001 bottom attachment. Take a look at the image below to determine which balance you'll need. You'll also need to weigh your sashes to determine which strength options you'll need. There is a chart on the product page that explains how to choose your option based on the sash weight. Thank you!
