ABSTRACT:
An improved method of building a wooden door frame in a door opening of a building without shimming, and a precut and pre-assembled combination of wooden lintel and side post miter end assemblies, each comprising a jamb member with permanently installed outwardly extending mouldings, and if necessary a longitudinally extending doorstop on the main outer surface of the jamb member. The miter ends of the assemblies are precut at 45 degrees at the point of manufacture when all their wooden components have been permanently assembled together, each assembly has a longitudinally extending wide shallow groove for miter L-shaped clips whose horizontally disposed arms are secured to the lintel assembly prior to erection. The free arms of the L-shaped clips extend downwardly away from the lintel mouldings but as close as possible from the ends of the lintel assembly whereby, once the lintel assembly has been horizontally secured in place to the horizontal stud of a partition to be framed, the vertical arms of the L-shaped clips are received in the groove of the jamb member of each side post assembly to guide same so as to provide a perfect miter with minimum effort and time on the part of the carpenter. A cross-piece adjacent the miter end of each jamb member prevents warping thereof and defines, with the shallow groove that it bridges, a slot for receiving the free arm of the corresponding L-shaped clip.
