Thanks for posting, Gary.
Can you clarify the "9/8" measurement? Also, please give us the overall height of the guide and the depth of the cap.
The 9/8" measurement is 1 and 1/8" across the top (if the guide were a "T", the horizontal bar is 1 and 1/8"). The overall height is 1 and 3/8". I'm not sure what you mean by the depth of the cap. If you mean the horizontal measurement of the top in the middle picture, that's 3/4".
Let me know if you have any other questions or need further clarification.
Thanks,
Gary
Hi Gary,
I believe we found the needed replacement top sash guides, please allow a few weeks. We will post again as soon as they are available.
I too am needing this piece for 4 of my windows. Can't wait until you have them available.
