Step 4: Shim and Secure Lock and Head Jamb
a) Close the door and adjust the jamb so the weatherstripping meets the door evenly
from top to bottom.
b) From the inside place three wood shims between the frame and the studding at three
locations (Figure D).
c) Be sure to adjust the three shims to plumb jamb and provide a 3/16" margin between
the door and the jamb (Figure E).
d) Nail with 16 d finish nails through the lock jamb, shims and studding.
e) Nail head jamb and brickmold.
Step 5: Threshold Cap Adjustment
a) If necessary, the threshold cap can be adjusted. Adjustment is accomplished
by sliding a pocketknife blade or thumbnail under the flange of the screw
cover, to lift it off, as shown in Figure e.
b) Removing the screw cover will reveal the adjustment screw. Using a screwdriver
as shown in Figure F, the jack screws may be turned to adjust the threshold cap to the
desired height. Replace the screw covers.
