Need replacement part

Question

The window slides up and down. I believe it's called a channel block and tackle. The length is 33 inches and the width is just over 1/2 inch. The only markings I could find are the following

32 4 EW CMC 4

Thank you for your help.

Hello! We call this part a channel balance. Yours looks like it could be either our S380-33 or S385-33, depending on the depth of the bottom nylon fitting. That's the only difference between them. You'll have to measure your bottom fitting and refer to our dimensions to confirm the best choice.
