Abstract: AN ELONGATE LONGITUDINAL, PREFERABLY L-SHAPED CROSS SECTION AND PLASTIC TRACK IS SECURED AT AN UPPER EDGE OF A DOOR OPENING AND LONGITUDINALLY SLIDABLY SUPPORTS A DOOR THROUGH HANGERS FASTENED TO SAID DOOR. EACH HANGER IS INVERTED GENERALLY L-SHAPED IN CROSS SECTION ENGAGING UPWARDLY OVER A TRACK FLANGE AND DOWNWARDLY INTO SAID TRACK WITH A RESILIENTLY DEFORMABLY KEEPER PROJECTING GENERALLY TRANSVERSELY UNDERLYING AND ADJACENT SAID TRACK. THE KEEPER THEREBY NORMALLY RESTRICTS UPWARD MOVEMENT OF THE HANGER TO RETAIN ENGAGEMENT BETWEEN THE HANGER AND TRACK BUT IS RESILIENTLY DISTORTABLE UPWARDLY AGAINST THE TRACK FOR PERMITTING UPWARD MOVEMENT OF THE DOOR AND HANGER TO DISENGAGE SAID HANGER FROM SAID TRACK. THE HANGERS MAY BE FORMED UNITARY OF PLASTIC WITH THE KEEPERS

OF REDUCED CROSS SECTION FOR RELATIVE RESILIENCY AND THE REMAINDERS OF THE HANGERS INCREASED CROSS SECTION FOR RELATIVE RIGIDITY.
