Block and tackle channel balance

Question

Hi, I have block and tackle balances that are 28" in length and 1/2" in width, weight rating 2730. I can't identify the series because I don't see the right end components on your website. Can you help with this? I've already replaced these on my other windows but didn't realize the 3rd window was different. Thank you.

Thanks for your photos. Based on what I see here, you have either our S380-28, S385-28, or S378-28 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.
