A. Confirm the opening is plumb and level. Ensure
the bottom of the rough opening does not slope
toward the interior.
Note: For peak water performance it is critical the
bottom be level within +/- 1/16".
B. Confirm the door will fit the opening. Measure all
four sides of the opening to make sure it is 1/2" larger
than the door in width and 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.
D. Nail-fin Only: Fold the water resistive barrier (1D). Fold
side flaps into the opening and staple to inside wall. Fold
top flap up and temporarily fasten with flashing tape.

C. Nail-fin only: Cut the water resistive barrier (1C).
4th cut:
Make a 6" cut up from
each top corner at a 45°
angle to allow the water
resistive barrier to be
lapped over the fin at
the head of the door.

Opening Preparation on page 11.
E. Apply sill 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 sill 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 water
resistive barrier.
