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.
