I have matched the dimensions of all of the parts of my channel to your 30" Series 380 Channel Balance, but I need help figuring out which stamp option to choose. As best as I can make it out, the stamp on my existing part reads 29 - 3 EBS1

Thanks for your help!

With an option of 29-3, I recommend our 2930 option. Of course, you can always weigh your sash to confirm that this is correct.
