C. Cut the water resistive barrier.
REMEMBER TO USE APPROPRIATE PERSONAL PROTECTIVE EQUIPMENT.
A. Verify the opening is plumb and level.
Note: It is critical that the bottom is level.
B. Verify the door will fit the opening. Measure all
four sides of the opening to make sure it is 3/4"
larger than the door in width and 1/2" larger in
height. On larger openings measure the width
and height in several places to ensure the header
or studs are not bowed.
Note: 1-1/2" or more of solid wood blocking is
required around the perimeter of the opening.
Fix any problems with the rough opening
before proceeding.
