Looking for these sash guides. Measurements are 5/8" bottom width, 1 1/16" top width. One screw hole. (pictured unit is broken). The one I'm looking for has a small rectangular slit in it as shown in my pictures.

Hello,
Your top sash guide resembles our 18-108 pair. Take a look and see how our specifications compare to yours. Thanks for posting!
