Various aspects of the present disclosure are directed toward apparatuses, systems, and methods for installing a closure assembly into a framed opening having sheathing arranged around the framed opening. The apparatuses, systems, and methods may include use of at least one support bracket along the framed opening and the sheathing.

The present invention provides an improved method and apparatus for mounting a door frame into a door opening of a building and includes at least one mounting bracket, a door support frame, and a trim frame. The at least one mounting bracket is connectable to the door opening and provides mounting pins for engaging the door support frame. The door support frame provides a bracket connecting portion and a soffit engaging portion that are integrally constructed and connected to a soffit of the door support frame. The trim frame is adjustably connected to the door support frame by engaging the bracket engaging portion and the soffit engaging portion of the door support frame.

Installation systems and methods for fenestration units configured to be set into a rough opening from an interior side of a building or wall. The fenestration units may include a retention system coupled to the frame and operable to exert a retention force on the fenestration unit to maintain positive engagement of the fenestration unit with the rough opening framing and resist extraction of the fenestration unit from the rough opening upon insertion of the fenestration unit in the rough opening from the interior side of the rough opening.

A door frame system comprises a wall and a door frame. The door frame comprises a sub-buck portion and a shell portion, coupled to the sub-buck portion. The sub-buck portion comprises a sub-buck mounting arm including at least one mounting aperture, a sub-buck rabbet arm coupled to one end of the sub-buck mounting arm and a sub-buck support arm coupled to the sub-buck mounting arm opposite the sub-buck rabbet arm. The sub-buck portion is surface mounted to a single surface of the wall through the at least one mounting aperture.

A coupler (10A) couples a door frame (2) and an auxiliary member (8) on a wall side. The coupler (10A) includes a foundation member (20) arranged on the door frame (2), and a coupling member (21) having a length extending from the foundation member (20) to a side of the auxiliary member (8) and joined to the auxiliary member (8) by a joint (24, 25). The coupling member (21) includes a base portion (21A) arranged on the foundation member (20), and a coupling portion (21B, 21C) extending from the base portion (21A). The coupling portion (21B, 21C) can be bent with respect to the base portion (21A). The coupling portion (21B, 21C) bent to the side of the auxiliary member (8) with respect to the base portion (21A) is joined to the auxiliary member (8) by the joint (24, 25). This can simplify the structure of the building material coupler.

A fitting arrangement (5, 23) for a frame (3) of an openable element having a first fitting part (10) configured to be arranged onto the frame, and a fixation device (9). The fixation device includes a sleeve (26) having exterior threads and interior threads, the sleeve being configured to be attached to an opening in the frame (3) by the exterior threads, and a wall screw (12) configured to extend through the sleeve into a wall next to the frame, attaching the sleeve to the wall, and the wall screw is rotatable relative to the sleeve. A fitting screw (25) is configured to fix the first fitting part (10) to the sleeve by engaging with the inner threads of the sleeve.
