Window Channel Balance Top Sash Guide

A home owner from Drexel Hill, PA says:
I'm looking for sash guides for my non-tilt windows. Here are the measurements I took of the guide:

From the side, the guide is 1 3/8" long and 11/16" wide at the top portion.
From the front, the top portion measures 7/8' wide and the bottom portion measures 5/8" wide.

The top measures 7/8" by 15/16". Please let me know if you have this guide or which guide is the closest to it. Thanks.

Thanks for writing in. Start by looking at our 18-033. It looks like many of the dimensions match, but compare for yourself to confirm. Another possibility is the 18-110, but I think the 18-033 is probably the better bet. See what you think.

My sash guide does look like the 18-033. I will try that with my windows. Thanks.
