window balance identification

Quick Learner from Santa Barbara, CA
Hello, 
Can you help me identify these window balances?  One has a broken pully on a non-tilting sash window I have.
The metal channel is 24" long and it is 9/16 wide.
Thanks,David

Hi David,

Thanks for reaching out! The window balances you have can be replaced with either the S380-24 or the S385-24. To determine which of these is the correct replacement for your window, you'll need to confirm the depth of your bottom shoe.

Comparison of the S378, S380 and S385 balance shoes.

There appears to be two different stamps on your balance, so I am unable to determine exactly which one you'll need for the replacements. That said, you'll need to obtain the exact weight of the window sash to determine the weight range your balances should be able to support.

Please don't hesitate to reach out with any questions you might have.
