Abstract
A slidable door assembly for opening and closing an opening or entranceway including a hanger plate having hanger and up-thrust rollers thereon, a door panel fixed to the hanger plate, and a support structure disposed above the door opening. The support structure includes a hanger track upon which the hanger rollers travel, and a horizontally oriented guide or bearing surface which co-acts with the up-thrust rollers. A door stabilizer is fixed to the door panel, adjacent to its trailing edge, with reference to its closing movement, which includes a roller whose rotational axis is disposed outside the vertical projection of the door panel. The roller of the door stabilizer co-acts with a guide surface, which may be the same guide surface used by the up-thrust rollers, to protect the up-thrust rollers from excessive force, and prevent untracking of the hanger rollers, when a force is applied to the leading edge of the door panel.
