  • Patent number: 4438597
    Abstract: A door frame or jamb and hinge mount which is at once pre-hung and adjustable comprises a mounting bracket positionable immediately behind the body of the frame for rigid attachment to a hinge leaf disposed at a cutout in the frame and adjustable attachment to the frame body, via bolts. A cavity between the frame body and the structural material to which it is attached encompasses the mounting bracket and allows a range of vertical and horizontal adjustment, oversized adjustment holes allowing relative movement between the mounting bracket and the body when the bolts are loosened, notches in the periphery of the adjustment holes dimensioned to rest against the bolts attaching the bracket to the body, the notches indicating a known alignment of the hinge leaf and mounting bracket therefor, whereby the hinges can be set up at standardized positions and thereafter adjusted as required.
