Upper Door Guides
Thanks for posting. This reminds me of our 23-044 Sliding Mirror Door Top Guide. Compare with your old hardware and see if you think this could work for you.
My pleasure. Let us know how you make out, and thanks again for reaching out!
The 23-044 has a plastic guide already, visible in the diagram above. Yours is broken off, though, so I unfortunately cannot verify whether it's identical. Your next step should be to review an undamaged version of your guide to determine whether or not they're the same style.
Hello! Our 23-044 top closet door guide is adjustable, yes. According to my records it has four settings: 3/8", 5/8", 7/8", and flush.
Hopefully this information helps.
