1ROUGH OPENING PREPARATION

If replacing an Aluminum sliding door in hardcoat stucco, see Step 8 flush flange Opening Preparation on page 11.

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.

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.

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. 1D

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.
