Blick and tackle non tilt

Hello there. I'm confident we can help replace this channel balance, but I'd like to verify one detail. Can you show us pictures of the 'guts' or underbelly of the metal channel? I want to see how the metal spring and pulley system connect. Once we confirm one specification, we should be able to narrow this down for you. Many thanks. 

Thanks! Thanks for your photos. Based on what I see here, you have either our S380-15 or S385-15, 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.
