I am afraid we can't narrow down what patio door rollers you need without seeing them out of the door. Knowing the width and height of the assembly, as well as the diameter of the wheels, is also crucial. See the video below for details on how to remove and replace these rollers. For the mortise lock, see if the 82-218 matches what you need. |
