YM-00 ROLLERS

If you wanted to use this roller with a wall mount hanger, the door would be over an inch from the wall. With ceiling mount hangers the door can be as close to the wall as you want, and the hardware is all visible on the outside of the door.
If your door is very heavy you can also use the floor track as shown, along with the upper track.

YM-00 allows the door to come within a fraction of an inch of the ceiling.

Using the bottom roller requires using a track that is drilled and countersunk for the flat head machine screws.
We have track that is pre-drilled and track that is un-drilled. Using the pre-drilled track makes installation easy except that you need to have backing behind the sheet rock.
Using the undrilled track allows you to mount the hangers where you want - on the ceiling, but then you have to drill and counter sink the track yourself. The countersink required is larger than most common countersinks and the holes should be parallel.

The roller can also be used on floor with a stainless Half Track.
