Channel Block Tackle Window Balance

Question

Dear Representative,

I need to replace 8 of these for for windows.
the windows are all the same but one of the parts has a different stamp.
They are the original ones that were installed by the builder.
I think they may have used one different one by accident.
The windows are all the same size.
Do you know what size and weight I should order?
Thank you in advance for your help.

Thanks for your photos. Based on what I see here, you have either our S380-27 or S385-27, 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.
