C. Cut the water resistive barrier.
D. Fold the water resistive barrier. Fold side flaps into the
opening and staple to inside wall. Fold top flap up and
temporarily fasten with flashing tape.
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 (IE) so it overhangs 1" to the exterior.
Note: The tape is cut 12" longer than the width so that it will
extend 6" up each side of the opening.
F. Tab the sill flashing tape and fold. Cut 1" wide tabs at each
corner (1/2" from each side of the corner) (1F). Fold tape to
the exterior and press firmly to adhere it to the water resistive
barrier.

If the wall depth is greater than 5", add a third piece of
