Identifying Channel Balance For Replacement

A quick learner from Hawaii says:
Hello~ I need help confirming if I need Series 351 or 390. I can't seem to see the difference between shoe #15-001 and 15-002. I don't know the sash weight range either. Help! Please tell me what I need to order, thank you! Here's some information for my channel balance:
Length: 33"
Width: 1/2"
Numbers on the back: 32 3 AV CMC 2

Thank you for posting. The difference between the 15-001 and 15-002 is found in their depths. Carefully compare their dimensions to your own shoe and see which is a better match.

As for the option, usually a stamp of 32 3 corresponds to our 3230. However, you should weigh your window sash just to make sure that's correct.

Aloha Tom,

Thank you for your reply and help in identifying what channel balance series I need to order. The dimensions you provided for the shoe depths confirmed that I need a 15-001. And, I'll be sure to double check the weight of my window sash before ordering. Thank you again!
