An assembly for a door or window frame including an elongated sill and a corner key attached to each end of the sill. The corner key includes a water chamber for collecting water therein and a plurality of ports for diverting water from the water chamber outwardly through a drain port. The water chamber and plurality of ports are designed to temper a high-pressure gradient in the sill and effectively promote water egress away from the sill.

A kit for a frame assembly is disclosed. The kit comprises a first frame member, a second frame member, and a first and second counterpart of a corner connector. The first and second counterparts are co-operatively configured for connecting to obtain the corner connector. The first counterpart, the second counterpart, the first frame member, and the second frame member are co-operatively configured for assembly to define the frame assembly. The first frame member is coupled to the second frame member via the obtained corner connector. The corner connector is connected to the first frame member along a first side of the first frame member and is also connected along a second side of the first frame member, and the corner connector is connected to the second frame member along a first side of the second frame member and is also connected along a second side of the second frame member.

A frame door with a split connection frame is provided, including a split connection frame. The split connection frame includes a first connection frame which is provided in a frame door and a second connection frame which is provided in an other frame door. The first connection frame is provided with a slide rail groove, the second frame is provided with a slide plate which engages with the slide rail groove. The slide rail groove has a C-shaped cross section so as to wrap edges of the slide plate. By using the split connection frame design, and using the sliding connection solution of slide rail groove and slide plate, on the one hand, the operation is convenient, time and labor are saved by the preset slide track during mounting process. On the other hand, the frame door is enable to be positioned in the mounting process via the preset slide track, thereby avoiding the assembly error caused by improper operation when using the existing mounting method and improving the assembly accuracy.

System for plugging an opening, including: a plug element designed to cover said opening, a frame made up of at least four rails (1′) designed to be positioned inside the opening and including a first groove (22) formed on a front wall of each rail, and a seal (29),
said first groove (22) being designed to accommodate a substantially peripheral part (27) of the plug element, said seal (29) being designed to be accommodated with a tight fit in retaining means (34) inserted in said groove (22) and retaining said plug element on the frame.

A Dutch door assembly includes first and second door sections, each including a composite door member and an end cap. The composite door member includes a core member disposed between first and second end stiles, together defining a front door surface, a rear door surface, and an end surface, a front door skin secured to and substantially covering the front door surface, and a rear door skin secured to and substantially covering the rear door surface. The end cap includes a cover portion covering the end surface of the composite door member and a retention portion extending from the cover portion into engagement with the core member. The end cap of the first door section includes an abutment portion contoured to engage an abutment portion of the end cap of the second door section when the first and second door sections are in pivoted alignment.

Disclosed is a threshold assembly that is durable and resistant to damage from mechanical stress and ultraviolet light exposure, thermally insulating, aesthetically pleasing, and adjustable to accommodate varying door heights and entryway dimensions and that can also be manufactured in a cost effective manner. The threshold includes base portion having a front face that accommodates an extender, a top surface, a channel, a nose wall, and an optional sizing notch that allows the threshold to be cut to varying entryway widths. The threshold further includes a deck cover secured about the base portion and a cap disposed within the base channel. An adjustment screw is disposed within the cap and used to vary the height of the threshold assembly to create an appropriate fit to an associated door. The deck cover or other components can be made of a durable coextruded material with impact or other modifiers.

A system, device, kit, assembly and methods for a frame assembly, including a door sill as shown and described. The assembly may be a door frame assembly and may, by way of example, be a door jamb and/or a door mullion including a door sill. Some inventions of the present disclosure may be a configurable door sill. In some embodiments, a door sill includes a base and a configurable insert component.
