1 ROUGH OPENING PREPARATION

A. Conﬁrm the opening is plumb and level.

Note: It is critical the bottom is level.

B.Determine the ﬁnished ﬂoor height. If the

ﬁnished ﬂoor height will be more than 1" higher than the surface the door will be set on, add a ﬁller board under the sill. The top of the ﬁller board should be within 1" of the ﬁnished ﬂoor height.

C. Conﬁrm the door will ﬁt in 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. Measure the opening width in several places to ensure the studs are not bowed.

Note: 1-1/2" or more of solid wood blocking (studs) is required around the perimeter of the opening. Check the wall for plumb and the opening for square by checking opening diagonal measurements. Fix any problems with the rough opening before proceeding.
