Mounted for vertical adjustment upon an angle member previously installed in an elevator shaft below an entrance opening thereof is an upward-facing flanged channel sill support upon which rests an entrance door sill. Secured at right angles to the sill support in spaced parallel relationship and projecting outward therefrom into the entrance opening are two angle brackets, each with a plurality of horizontally spaced keyhole slots in its vertical flange. Detachably secured to each such vertical flange by headed screws seated in the keyhole slots is the lower end of a channel door jamb of an elevator entrance door frame. Tiltably insertably into a groove of L-shaped cross-section in the inner edge of the sill is the L-shaped upper end flange on an upper facia panel. Slidably mounted on the upper facia panel for vertical adjustment relatively thereto is a lower facia panel, the lower edge of which rests upon the upper edge of the unfolded Z-shaped hanger head of the elevator entrance structure of the floor immediately below.
