Swisco, please find the attached pictures of my "channel balance" system. I still can't see if it has "shoes" or not, the measurements are 19" long and 1/2" wide, marked # is 1740. Old up/down non tilted sliding windows to be repaired. That's all I know. Looking forward to your opinion and I will need 4 replacement parts with top and shoes.
I'm talking to a Swisco rep but he won't help me because he doesn't see the shoes. But you're the experts. Why can't you tell me what I have?
