Window Channel Balance 32 5 AU CMC 2, the length is 33 inches.

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.
