An apparatus for installing door frames which comprises at least two template members and at least three apertures on each template member. To provide horizontal adjustment means between said at least two template members, at least one elongated member may be joined approximately normal to each of said at least two templates. Said at least one elongated member may comprise at least one tongue member and at least one groove member, said at least one tongue member may be slidably positioned within said at least one groove member. To provide means for plumbing said template members, at least one screw may be positioned within said at least one template member. To install a door frame, the apparatus is positioned within a doorway, said doorway composed of two trimmer studs joined by a header stud, such that the at least one template of the apparatus is juxtaposed one of the two trimmer studs, and said at least one aperture outlines the perimeter of at least one slot to be cut in the trimmer stud. Using said at least one aperture as a guide, at least one slot is cut in the trimmer stud using, e.g., a router or saw. At least one shim is inserted into said trimmer stud. The apparatus may be removed (preferably before shim installation) and the door frame member is installed, said door frame member juxtaposed said at least one shim. Before cutting said at least one slot in the trimmer stud, the installer preferably ensures that the at least one template member of the apparatus is plumb by turning the at least one screw which contacts the trimmer stud and adjusts the at least one template member until the at least one template member is plumb. The door frame may then be plumb and square with a door. |

DETAILED DESCRIPTION The present invention discloses an apparatus for installing door frames which may comprise at least one template member having a first end, a second end, and at least one aperture formed therein.
The apparatus preferably comprises at least two template, members.
The apparatus preferably comprises at least three apertures on each template member.
The apparatus may further include means, joined to said at least two template members, for horizontally adjusting said at least two template members relative to each other.
Said horizontally adjusting means may include, but is not limited to, at least one elongated member joined approximately normal to each of said at least two templates.
Said at least one elongated member preferably comprises at least one first member and at least one second member.
In one embodiment said at least one first member may be slidably positioned within said at least one second member.
Securing means such as, but not limited to, at least one set screw 99, bolt, pin or clamp may be used to secure the at least one first member and the at least one second member in their desired positions.
For example, said securing means may be positioned through one of said at least one first or second members to secure the at least one first and second members in their desired positions by friction.
In an alternative embodiment, said at least one first member and said at least one second member comprises at least one hole located therein.
Said securing means may be positioned through said at least one hole thereby securing said at least one first member and said at least one second member in place.
Said securing means may include a hand retractable spring plunger which includes a pin and locking mechanism employing biasing means such as a spring to ensure the pin stays in place when pressed.
The preferred positions of said at least one first and second members are the positions that result in the at least two template members being substantially parallel.
The apparatus may further comprise means, joined to each of said at least two template members, for plumbing said template members
