I am looking for the attached balance shoes. They are in PermaGuard windows in Florida. The coil appears to be the 150 series. The sizes on the shoe are 1-1/4" wide 2-1/4" high 11/16 deep.

It's hard to tell what the shoe is without seeing it removed from the window, but check out our 15-140 and see how well this matches.
