This is a set of handed white plastic guides that have a spring-loaded insert tip that fits bottom grooved tracks. They mount into the back bottom frame section of steel panel style doors and are held in place by a screw. Used on Glide-All door systems.
Almost given up on finding replacement parts for doors installed in the 70's until I just did a google search for the part name and wafair was listed as having the part! Clicked on picture/ad and the part came up exactly like the old broken parts, but new! Bought enough guides to repair closet doors in two bedrooms. Works very well, maybe will get another 40 or so years use!!. Marvin. Rio Rancho, NM. Thu Feb 06 2025
