Stanley wood mirrored sliding door top roller glide
Hello,
It looks like your wood door manufacturer may have taken part of the 23-222C from the metal housing and screwed the nylon piece to the door. Unforutnately, we do not carry the adjustable portion separately but take a look at the specifications from our product page below. Thank you.
The black adjustable piece that holds the rollers is riveted onto the metal bracket. You would need to drill it or grind it off the bracket. As for the size of the black piece, it is 3/4" wide and 2-1/2" tall. I wonder if you could swap out the rubber tires on the original housing with ours. The rubber tire on the 23-222C is 3/16" thick. The inside diameter of the hole is 5/16" and the outside diameter is 11/16". Take a look to see if one of these options might work for your repair.
