A perimeter replication device for a frame having an adjustable frame that includes a plurality of elongate members, and a plurality of hinges connected to the plurality of elongate members. Each elongate member is connected at a first end to a first hinge of the plurality of hinges and at a second end to a second hinge of the plurality of hinges such that the adjustable frame is substantially a continuous structure. Each elongate member are telescopic. The perimeter replication device further includes a locking unit configured to lock the adjustable frame in a locked configuration. The locking unit has an elongate member locking mechanism that locks each elongate member in any position between a telescopically unextended configuration and a maximum telescopically extended configuration and a hinge locking mechanism that locks each hinge. Further disclosed is a method for replicating the perimeter of a door frame.

A self-aligning jamb jack apparatus with a cylindrical threaded adjustment component that has adjustment component threads on the exterior wall and smooth surface on the interior walls, the cylindrical threaded adjustment component extending through a cylinder with a smooth exterior to a ball (or cut-off sphere), the smooth surface extending through the cylinder and the ball (or cut-off sphere). The jamb jack apparatus also has a platform base with a socket configured to encompass the ball (or cut-off sphere) such that the platform base pivots around the ball (or cut-off sphere). The self-aligning jamb jack apparatus is installed in a door or window jamb (or any other appliance) to connect and regulate the space between the jamb and the rough framing.

An apparatus to install a door jamb is disclosed. The apparatus may include a body portion, a first extendable arm and a second extendable arm. The first extendable arm may be disposed at a body portion distal part and the second extendable arm may be disposed at a body portion proximal part. Each of the first extendable arm and the second extendable arm may be configured to slide between a retracted position and an extended position. The apparatus may further include a first angle finding device and a second angle finding device configured to determine angle of the apparatus relative to ground. The first angle finding device may be attached to a first extendable arm distal end, and the second angle finding device may be attached to a second extendable arm proximal end.

A door trim installation system includes a right-angle bracket that includes a first leg and a second leg, an angled reinforcement structure attached to and reinforcing the first leg and the second leg, and a securing assembly to temporarily secure the bracket to a door frame. Each of the first and second legs includes an outer surface abuttable against an interior surface of a corner portion of a door frame. The first leg includes a support shoulder designed to project out beyond a door frame and upwardly over a reveal to provide an alignment and support surface for a top piece of door trim or moulding to be installed.

A door set for installation in a doorway in a wall. The door set comprises a door liner arranged to be mounted by its outer edges to the wall adjacent the doorway, and further arranged to have a door movably mounted to an inner edge; and at least one door alignment tool, comprising a base plate, at least one prong extending from a face of the base plate, and at least one alignment fixing on the base plate. The at least one prong is arranged to be inserted into a corresponding at least one bore in one of the door liner and the wall. The door alignment tool is arranged to be removably and adjustably secured to the other of the door liner and the wall adjacent the doorway using the alignment fixing.
