-The upper side of the kick plate railll is capped by a glass-carrying rail 2l of. the type previously described, which fits over the flanges l2 of the rail 3|; and is held to the rail 30 by screws l5.

After the glass-carrying rails 2l Iare in place around the four sides of the light opening, the

glass 38 may be set-in place with its edges fitting over the channelgrooves 24 and one side resting against the curved retainer 31 which projects from one side of the glass-carrying strip 2|. Separate glass-retainer strips 38 of the shape shown' in Fig. 8 are then placed as shown in Fig.

As the result of the principles of construction used in this door all parts can be kept in stock machined to standard widths and thicknesses, subject to being cut to required lengths for the production of a door of any desired size.

It will be clear to those skilled in the art that the frame may be made of steel or any preferred strong material, and that the sheathing sections may be extruded or molded of any suitable metal or plastics.

If the sheathing sections are extruded from aluminum they may be given a treatment known as anodizing which gives the aluminum an attractive and durable surface. The design is such that all of the aluminum parts'can be anodized before final assembly. This is advantageous because an aluminum product cannot be anodized after any metals or substances other than aluminum have been assembled with the aluminum.

I claim:

1. In a door of the type in which a frame is covered by a sheathing, the improvement which comprises, a frame member, a unitary homogeneously integral sheathing section having a substantially U`shaped cross section tted over the outer edge and sides of the frame member, and a glass-carrying cover strip interfitted with the edges of the sheathing section. Y
