An extruded aluminum sill member is supported by and attached to a wood base member which also supports a longitudinally extending inner wood trim member. The sill, base and trim members define a longitudinally extending cavity which receives a vertically adjustable rail member. The rail member has longitudinally spaced captive screws which are threaded into inverted T-nuts confined within laterally extending slots formed within the wood base member, and the trim member covers the slots. The sill member also extends under a jamb or mullion and a fixed side panel, and a snap-in extruded plastic cap covers the cavity under the panel and has an upwardly projecting and inwardly curved flange with a flexible lip for engaging the outer surface of the panel to form a water-tight seal.
A threshold assembly adapted to be installed below a bottom surface of a moveable door and a fixed panel, comprising an elongated metal sill member including a sloping top surface, a longitudinally extending base member under said sill member and cooperating with said sill member to define a longitudinally extending and upwardly facing cavity, an elongated rail member disposed within a first portion of said cavity adapted to be under the door, means for adjusting said rail member vertically within said cavity and including a plurality of longitudinally spaced threaded fasteners rotatably supported by said rail member, means forming a plurality of longitudinally spaced threaded holes within said base member and receiving said fasteners, an elongated cap member of extruded material and connected to said sill member for covering a second portion of said cavity adapted to be under the fixed panel, said cap member including an integral flange projecting upwardly from said sill member, and means forming a water-tight seal between said flange and the outer surface of the fixed panel.
