The balance channels in our sunroom windows are toast. They're half-in deep and 29 inches in length and have "2840S" stamped into them. Each window had one per side, from what I can tell, but they've all fallen out. I was hoping you stocked a compatible replacement.

The metal portion is 28-7/8" long. It is 1/2" wide. The only markings are "28 2 GK Caldwell" and the windows are single pane, aluminum frame and about 30 years old.

Hi, I spoke with you a couple of weeks ago about replacing some channel balances. I uploaded three pictures of the balance, a Caldwell 28-4 EM. Inside it has a spring and string mechanism.Thanks,David
