Abstract: An astragal boot provides a substantially weatherproof seal at a lower end of a vertically elongated astragal installed on the free side edge or stile of a semi-active door in a double door entry set or the like. The astragal boot includes at least one and preferably multiple compliant fins for engaging an underlying threshold, when the semi-active door is in a closed position, to provide an effective barrier against penetration of wind and water. In the preferred form, the astragal boot further supports and retains adjacent ends of complaint weatherstripping mounted on the astragal and/or the bottom edge of the door. The astragal boot may be provided in a non-handed configuration for reversible mounting on a left-hand or right-hand installed semi-active door.

Abstract: A sliding door assembly having a frame including a head jamb, a bottom sill, two vertical side jambs and a third center jamb for strength and rigidity of the overall frame. A fixed glass panel is mounted in a portion of said frame and a sliding glass panel mounted upon roller structure is mounted in another portion of the frame. The sliding glass panel has an extending fin around at least three sides thereof for cooperative association with weather seal structure provided with the non-movable portions of the assembly. The aluminum sill structure has self-draining slots therein and a replaceable plastic member is provided with the sill for ease of sliding of the sliding glass panel, as well as easy replacement thereof, if needed. Draining slots are also provided in the plastic member which are staggered relative to the slots in the aluminum to minimize wind blow through. The door assembly has an aluminum exterior and a wood interior, with the wood portion being removably attached by spring clips.

Abstract: Muntin bar molded anchors are installed on the interior edges of a window sash or sliding door frame by utilizing a two-part anchor holding and nail driving device which is stabilized during use. Molded clips are frictionally installed in recesses formed in the ends of muntin bars and the clips are snap locked over crowned surfaces of the anchors to complete the installation of the muntin assembly.

Abstract: To maintain a premanufactured sliding sash window assembly square and distortion-free during shipment and until completely installed in a building, the two vertical sides of the window frame are connected by a tension element which prevents outward bowing of the two frame sides. Protective clips are installed on the top and bottom rails of the exterior sliding window sash near the corners of the sash and are secured to the sash by adjustable clip and sash encircling bands. The upper sash clips include posts which are releasably anchored to interior faces of the window frame. The upper and lower sash clips include vertical spacing fingers which engage between the vertical edges of the exterior sash and opposing vertical faces of the window frame to provide proper spacing of the exterior sash relative to the vertical sides of the frame.

Abstract: Muntin bar molded anchors are installed on the interior edges of a window sash or sliding door frame by utilizing a two-part anchor holding and nail driving device which is stabilized during use. Molded clips are frictionally installed in recesses formed in the ends of mountain bars and the clips are snap locked over crowned surfaces of the anchors to complete the installation of the muntin assembly.

Abstract: A metal clad foam-filled fabricated door panel utilizes scrap metal generated in another product line to form a simulated stile and rail door having a very realistic appearance. The stile and rail metal cladding components are mechanically held together by swedging until wooden framing elements are installed and glazing is completed. Foaming of the panel is then carried out and all components are strongly bonded in assembled relationship by the cured foam.

Abstract: Sliding doors of increased strength, stability and resistance to the elements include on the normally inactive sliding door panel top and bottom vertical axis locking bolts which engage in apertures at the top of the door frame and sill. An intermediate level swinging bolt on the active sliding door panel is used in conjunction with an adjacent anti-lift tab also on the active sliding door panel. This tab and the locking extension of the swinging bolt are received in apertures formed in the adjacent stile of the inactive door panel to achieve secure locking of the sliding panels in closed positions. All of the bolts of the system are disposed within the opposing interfitting vertical stiles of the active and inactive sliding panels adjacent to tongue and groove portions thereof. The locking arrangement can be utilized on sliding door systems containing four or more panels.

Abstract: Opposing steel door skins are punched to provide openings of the required size for a specified lite unit. Lite unit locator and retaining flanges are simultaneously formed on the two skins. A prefabricated lite assembly consisting of a pane of glass and surrounding mitered wood frame with sealant is placed between two steel skins in interlocking engagement with the locator and retaining flanges and the door is put through a foaming operation to produce an interior foam core around the margins of the lite assembly or unit.

Abstract: An energy efficient, secure and economical patio door features hinged and fixed door panels with a strike mullion connected to the fixed door panel through a metal stiffener and with the strike mullion forming an integral part of the door frame by being tied thereto through head and sill members. The assembly is reversible end-to-end and therefore non-handed. The number of door panels can be increased or decreased and the assembly is fully weather-stripped.

Abstract: Prior to foaming, a unitary molded plastic liner or dam for the lockset cross bore and edge bore of a foam-filled metal skinned insulated door is installed between the metal skins in registration with accurately located pre-punched skin openings. The edge bore lining extension of the device is inserted into a preformed opening of the wooden stile for positioning the device. The device prevents insulating foam from entering the cross bore or intersecting edge bore in the subsequent foaming operation. Significant reinforcement is also provided between the metal skins of the door to prevent buckling of the skins during the installation of door hardware.

Abstract: To replace the customary wood bottom rail of a foam-filled metal skinned door, a prefabricated metallic bottom rail and Neoprene bottom sweep unit is utilized. The unit forms a closure for the bottom of the door panel during foaming and provides a better bond with the foam core and better anchorage therein.

Abstract: Preassembled self-locking guide and pivot pin cartridge assemblies are installed on the job site in folding doors rather than on the factory assembly line. Considerable labor is saved in manufacturing and a better installation is achieved. Both the guide and pivot pin assemblies feature molded nylon housings which conveniently snap into place on the folding door brace structure. Top and bottom guide pin assemblies are identical and interchangeable. A lower adjustable pivot pin assembly possesses more than one and one-half inch of full threads on the molded nylon housing and includes a hardened steel lock clip having snap on engagement with the housing and threaded engagement with the adjustable screw-threaded pivot pin. A cooperating lock nut is provided to secure the assembly after proper adjustment. Both of the guide and pivot pin cartridge assemblies are insertable as units on the doors and can be removed if necessary.

Abstract: A metal reinforcing plate is arranged beneath the usual striker plate in a routed recess of the wooden door jamb. The reinforcing plate has integral anchoring prongs which are driven into the wooden jamb immediately ahead of the stop rail and has additional anchoring and locator tabs which are received at the side walls of the bolt receiving recess or socket in the door jamb. The reinforcing plate is substantially concealed from view while imparting to the door structure substantial extra strength against forceable entry.

Abstract: A vertically adjustable threshold member or bar is shipped in a down position and is adjusted upwardly at installation by attached shouldered leveling screws engaging within flared T-nuts of base or sub-structue. A compressible seal is interposed between the outer longitudinal edge of the adjustable threshold member and an extruded metal sill. The outer longitudinal edge of the threshold member is beveled slightly for increasing pressure on seal as threshold member is raised.
