I believe the 10-216 was used by Southeastern on their shower doors. I'm not sure if they could be used as a universal fit for other shower doors. I would guess to use two per door at the bottom, but I don't know if you would have remove the bottom stile off the door to install these or if they just snap into the bottom of the door. If you want send us some photos of the glides you have on your shower door so we can identify the part needed.
