Abstract: 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.

Abstract: An extruded aluminum elongated sill member is supported by a wood base member and includes a sloping top wall integrally connected to a lower base wall positioned within a recess in the wood base member. A longitudinally extending wood trim member is attached to the wood base member and cooperates with the lower base wall to define a longitudinally extending cavity which receives a vertically adjustable rail member. The sill and rail members define corresponding longitudinally extending adjacent slots, and a longitudinally extending sealing member of extruded plastics material includes opposite semi-rigid edge portions with flexible fins which are pressed into the slots. The edge portions are integrally connected by a flexible U-shaped intermediate portion which is confined between the sill and rail members and forms a rolling diaphragm for vertically adjusting the rail member while maintaining a positive water-impervious seal therebetween.

Abstract: An elongated extruded door sill member is supported by a wood base and includes a sloping top wall and a rear wall connected by integral channel portions and a thermal barrier. The channel portions and barrier cooperate to define an upwardly facing cavity, and strips of resilient closed cell foam material are mounted within the channel portions. A vertically adjustable rail member extends longitudinally within the cavity and has side flanges projecting downwardly into the foam strips to form fluid-tight continuous seals. Opposite end portions of the rail member carry pads of the resilient foam material between the flanges for engaging the strips, the channel portions and the thermal barrier to form fluid-tight seals at the ends of the rail member.
