Now that the weather is warmer, one of my garage sliders is dragging a bit towards the end of its travel. I noticed that the door is hung on a threaded rod that goes into the caster. This seems to imply a facility for adjustment. Does anyone know how to adjust the hanging height of these doors without removing them from the tracks?
-n.
If I recall correctly, the way I did it was to put a block of wood under the door to shim it to the height I wanted then I loosened the jam nut on the threaded rod and finally adjusted the height by screwing the other nut as required. When done, remove the shim.
It has been a while, but I vaguely recall that the hole the threaded rod hangs from is slotted. Or maybe it is how the rod attaches to the door. But I think you can also make minor adjustments in and out incase the doors are rubbing or one door is rubbing on the center support post.
Did you have to remove the door to get to the lower nut?
I think you can use an open end wrench to get to that nut. You should avoid removing the door if you can possibly do so. And I certainly did not remove the door though I might have removed the hanger piece that holds the door to the track. It has been a while since I did this and my memory is a bit vague.
Got it! I actually couldn't get in with a wrench, but once the tension was off the lower nut, I simply turned it by poking it with a screwdriver.
