Please help me Identity a replacement channel balance

Question

Good evening, my name is Cindy. I just find out seven of our houses windows's Channel balance are broken. I don't know which one I need to purchase. I send you two pictures, length 29 inches, please help me identify the replacement. I already took old pieces, but they kind looks different. I try to replace all of the windows, just don't know which one I need. Thank you very much.

Hey, Cindy! Sounds like you already did all the hard work for us. I agree that the S380-29 looks like our best option. As for the stamps, you can usually match that that letter up with one of our numbers. For example, 28B would be our 2820 option, and 28C would be our 2830. Here's a handy rubric rubric you can use:

A = 10
B = 20
C = 30
D = 40
E = 50
F = 60

Hopefully that makes sense. You can, of course, weigh your sashes to be 110% sure, but I don't think that's necessary work at this point.

Let me know if you have any questions!
