HARDWARE INSTALLATION Hinges must be the proper size for the weight of door they support. For 35 mm (1 3⁄8 in.) thick interior doors, use two 76 × 76 mm (3 × 3 in.) butt hinges. For heavier doors, use three hinges. Fit the door into the jamb opening to ensure it has the proper clearances, then remove it and install the hinges. If not factory prepared, mortise the door to nest the half hinges. The edge of each hinge should be at least 3 mm (1⁄8 in.) back from the face of the door. When the hinge halves are screwed in place, they must be flush with the surface and square.
Place the door in the opening and shim it at the bottom to provide the proper clearance. Mark the jamb at the hinge locations and mortise it to accept the other hinge halves and screw them into place. Place the door into the frame and insert the hinge pins. To install the knob/handle and latch, mortise an inset for the latch and attach the latch and knob/handle. Mark the latch location on the jamb, and mortise an inset for the strike plate (Figure 171) and affix it so it is flush with or slightly below the face of the jamb. When the door is latched, the face of the door should be flush with the edge of the jamb.
