This piece is rubber with one screw that attaches inside the upper track of a sliding glass closet door. I believe its purpose is to keep the door from wobbling in the track as the outer edges will lightly brush against the track sides. There are two of these rubber pieces; one at each end. I somehow lost one. Thanks!

Hello, thank you for posting!
I cannot guarantee we have a proper replacement for this part, but are you able to show us the part installed on the door? Thank you!

Hello,
Unfortunately we could not find an exact replacement for you top guide. Take a look at the screw on top guide 23-226 and the snap-in top guide 23-079 to see if you could use one of these for your door. Let us know what you think!
