Channel balance replacements

Question

Hello,

I have windows throughout the house like picture 5.

A few have begun failing to smoothly open / close, and in one the spring inside the channel broke outright.

I'm looking to replace the broken channel balances and have a store of a few extra incase other balances fail.

the stamp says 32 4.

However, I measure 33inch for the full metal piece.

Can you help me determine the exact part for all my windows? thanks

Thanks for your photos. Based on what I see here, you have either our S380-33, S385-33, or S378-33 depending on the depth of the bottom shoe. That's the only difference between them. I recommend measuring your shoe and referring to our dimensions to confirm the best match.
