INSPECT ROUGH OPENING (R.O.)
The use of a sill pan and other barriers will decrease
the rough opening height clearance. Adjust the
opening dimensions accordingly.

the patio door width and height.
• Verify the rough opening
Verify Square, Level and Plumb

C
E
level and plumb (C, D and E).
Suggested deviation is no more

(positive slope) to the exterior.
• The exterior face of the rough opening should be in a single plane (E)
with less than 1/8" twist from corner to corner.

For Retrot Installations
Verify the rough opening framing is structurally sound. Contact your local

This installation guide only addresses masonry/block wall, sheathed
wall, open-stud construction and exterior foam insulation. For
exterior foam insulation construction, please reference the latest
version of FMA/AAMA/WDMA 500 for additional install and
framing details. If installing into an opening other than what is
identied, consult a building professional.
Masonry/Block Wall Construction
This installation assumes
that a framework of
studs (often called a
buck) has already been
properly fastened in a
weatherproof manner to
the concrete/masonry wall.
Buck
The patio door will be
mounted into the buck in a
weatherproof manner.
Fully Sheathed Wall Construction
