The method also includes inserting the pre-hung door into the rough opening at the job site and attaching the mounting brackets to the rough opening to support the door panel for opening and closing before the door frame is attached to the rough opening. ## Claims ### Claim 1 A method for installing a pre-hung door assembly in a rough opening at a job site, the method comprising the steps of: performing at a location remote from the job site the steps of positioning a door frame around a perimeter edge of a door panel and attaching the door panel to the door frame with a plurality of hinges to comprise a pre-hung door; retaining the door frame square with respect to the door panel; attaching a plurality of mounting brackets to the pre-hung door; inserting the pre-hung door assembly into the rough opening at the job site; and attaching the mounting brackets to the rough opening to support the door panel for opening and closing before the door frame is attached to the rough opening. ### Claim 2 (depends on 1) The method of claim 1 comprising the step of inserting the pre-hung door from an interior side of the rough opening. ### Claim 3 (depends on 1) The method of claim 1 comprising the steps of attaching the mounting brackets to an interior surface of the rough opening. ### Claim 4 (depends on 1) The method of claim 1 comprising the step of attaching the door frame to the rough opening. ### Claim 5 (depends on 1) The method of claim 1, wherein the mounting brackets are initially provided in a folded configuration for transportation, the method further comprising unfolding the mounting brackets to an open position prior to securing the mounting brackets to the rough opening. ### Claim 6 (depends on 1) The method of claim 1 comprising the steps of: opening the door panel relative to the door frame; locating shims between the door frame and the rough opening; and attaching the door frame to the rough opening. ### Claim 7 (depends on 1) The method of claim 1 comprising pivotally attaching the mounting brackets to the door frame. ### Claim 8 (depends on 1) The method of claim 1 comprising rigidly attaching the mounting brackets to the door frame. ### Claim 9 (depends on 1) The method of claim 1 wherein the step of attaching a plurality of mounting brackets to the pre-hung door comprises attaching a plurality of hinges on an exterior perimeter surface of the door frame. ### Claim 10 (depends on 1) The method of claim 1 comprising pivotally attaching the mounting brackets to the hinges. ### Claim 11 (depends on 1) The method of claim 1 comprising rigidly attaching the mounting brackets to the hinges. ### Claim 12 (depends on 1) The method of claim 1 comprising pivotally attaching the mounting brackets to a door side plate and a door frame side plate of the hinge. ### Claim 13 (depends on 1) The method of claim 1 comprising the steps of: positioning the mounting brackets coplanar with a surface of the pre-hung door at the location remote from the job site; and positioning the mounting brackets parallel to a major surface of the door panel before attaching the mounting brackets to the interior surface of the rough opening. ### Claim 14 (depends on 1) The method of claim 1 comprising attaching at least one spacer to at least one of the door panel and the door frame. ### Claim 15 (depends on 1) The method of claim 1 comprising pre-drilling at the location remote from the job site one or more holes in the door frame to secure the door frame to the rough opening. ### Claim 16 A method of installing a pre-hung door assembly in a rough opening in a building, the method comprising: providing a pre-hung door assembly comprising a jamb assembly, a door, a plurality of hinges securing the door to the jamb assembly, and a plurality of mounting brackets for securing the jamb assembly to at least one building frame member adjacent the rough opening; inserting the pre-hung door assembly into the rough opening from an interior of the building; securing the mounting brackets to a first vertical frame member adjacent the rough opening using a plurality of fasteners; opening the door of the pre-hung door assembly after securing the mounting brackets to the at least one frame member; and securing the jamb assembly to a second vertical frame member positioned on an opposite side of the rough opening as the first frame member using a plurality of fasteners. ### Claim 17 (depends on 16) The method of claim 16 wherein the mounting brackets are initially provided in a folded configuration for transportation, the method further comprising unfolding the mounting brackets to an open position prior to securing the mounting brackets to the first vertical frame member. ### Claim 18 A kit for installing a door in a rough opening comprising: a door frame extending around a perimeter edge of a door panel; a plurality of hinges attaching the door panel to the door frame comprising a pre-hung door assembly; and a plurality of mounting brackets attached to the pre-hung door frame, wherein the mounting brackets attached to the interior surface of the rough opening support the door panel for opening and closing before the door frame is attached to the rough opening. ### Claim 19 (depends on 17) The kit of claim 17 wherein the mounting brackets are pivotally attached to the door frame. ### Claim 20 (depends on 17) The kit of claim 17 wherein the mounting brackets are rigidly attached to the door frame. ### Claim 21 (depends on 17) The kit of claim 17 wherein the mounting brackets comprises hinge extensions pivotally attached to the hinges. ### Claim 22 (depends on 17) The kit of claim 17 wherein the mounting brackets comprise a plurality of hinges mounted on an outwardly facing, perimeter surface of the door frame. ### Claim 23 (depends on 17) The kit of claim 17 wherein at least one of the mounting brackets comprises an L-shaped bracket. ### Claim 24 (depends on 17) The kit of claim 17 wherein at least one of the hinges comprise a door side plate, a door frame side plate and at least one of the mounting brackets attached to one of the plates.
