These door‘ units ordi narily consisted of a door panel hung from an overhead track by means of several spaced rollers, and adapted to be slid into a central housing space provided in the wall adjoining the door‘ opening. In some instances, the overhead guide tracks were formed directly on the wooden head jambs or door headers, but the suspension rollers which coacted with these tracks and the hangers which united the rollers with the door panel, were universally formed of metal such as die castings. The material from which these die castings were made has become di?icult to obtain, and the same installation thereof.‘ - I v 1 These and other objects and advantages of this invention will be apparent from the following de tailed description. ~ ' ' v A clear conception of the several features con 20 stituting the present improvement, and of the mode of constructing, installing and of manipu lating sliding doorunits built in accordance with the invention, may be had by referring to the drawing accompanying and forming a part of this I speci?cation wherein like reference characters designate the same or similar parts in the various views.
