ROUGH OPENING PREPARATION
A. Confirm the opening is plumb and level.
Note: It is critical that the bottom is level.
B. Confirm 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. Measure
the width at the top, bottom, and center. Measure the height at the far left side, the
far right side, and in the center.
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.
C. Apply flashing paper at the bottom (1C). Cut one piece of flashing paper 18" longer
than the width of the rough opening. Position the top edge of the flashing paper with
the top of the sill plate. Center the flashing paper with the opening width. Staple the
flashing paper to the sill plate.
Note: Bottom flashing paper is not required for installation on concrete floors.
D. Apply flashing paper to the sides of the rough opening (1D). Cut two pieces of
flashing paper 18" longer than the height of the rough opening. Apply one piece to
each jamb. Position the edge of the flashing paper with the inside edge of the trimmer
(jack stud), and center the flashing paper with the height of the rough opening. Staple
the flashing paper to the trimmer.
E. Apply bottom flashing tape #1. Cut a piece of flashing tape 12" longer than the opening
width. Apply at the bottom of the opening as shown (1E) so it overhangs 1" to the exterior.
Note: The tape is cut 12" longer than the width of the opening so that it will extend up
each side approximately 6".
F. Tab the bottom flashing tape and fold. Cut 1" wide tabs at each corner (1/2" from each side
of corner) (1F). Fold tape to the exterior and press firmly to adhere it to the flashing paper.
G. Apply bottom flashing tape #2. Cut a piece of flashing tape 12" longer than the opening
width. Apply at the bottom, overlapping tape #1 by at least 1". DO NOT allow the tape to
extend past the interior face of the framing (1G).
Note: The flashing tape does not need to extend all the way to the interior of the framing.
H. Attach the aluminum sill support or wood blocking to the exterior of the box plate
to support the edge of the door sill. Place the sill support flush with the subfloor.
