Abstract: A multi-component door frame assembly, including a door jamb having a length and contact surface. A plurality of ribs along the length of the door jamb and extending distally from the contact surface. A door stop detachably fixed to the door jamb and adapted to receive a door when the door is in a closed position.

Abstract: A screw attachment plug includes a proximal portion having a first diameter and a first height, a middle portion having a second, constant diameter, a second height and a means for preventing rotation of the plug relative to the substrate and the portion. The screw attachment also includes a distal portion including a distal end, proximal end, and an outer surface therebetween. The plug includes a bore through the proximal, middle and distal portions adapted to receive a screw and a plurality of slots in the distal section, each defined by an open space between the outer surface and the bore thereby separating the distal portion into a plurality of sections. The open spaces are adapted to expand when a screw is inserted into the bore to thereby expand at least the middle and distal portions within the substrate.

Abstract: A device for providing a seal between a door and at least a part of a doorway includes a door sash having a length, a hinged edge, a front portion, a back portion, and a plurality of curls on the hinged edge. The device also includes a door jamb proximal to the hinged edge, a door stop, a weather strip configured to engage the door sash and adapted to provide a first seal when the door is in the closed position, and a plurality of sealing members extending from the curls and adapted to provide at least a second seal between the door sash and the jamb.

Abstract: The invention relates to a framing member for attaching panelling and windows to building structures which includes an integral and detachable J-shaped member and nail fin which obviate the need for decorative molding to mask the junction between the framing member and the underlying building structure. The J-member and nail fin may be broken away from the framing member to allow framing members to be attached to one another via a mullion strip to define a mullion between windows or panelling.
