FRAME TWISTS
Attach two pieces of
string to frame/panel,
corner to corner. If
there is a gap between
strings at center point
larger than 1/8" for
patio doors up to
4' wide or high, or
3/16" for patio doors
larger than 4' wide
or high, the frame is
not at. Repeat by
switching strings and
re-measuring.
PROPER SHIMMING
Measure width of
frame at top, center,
and bottom. If any two
measurements differ
more than 1/16", the
frame is over or under
shimmed. Repeat
process and measure
height of frame.
LEVEL AND PLUMB
For plumb, place level
against each side jamb
or use a plumb bob. For
level, place level against
head jamb and sill.
SQUARE
Measure frame/panel
from top left to bottom
right corner and from
top right to bottom left
corner. If measurements
differ by 1/8" for patio
doors up to 20 sq. ft.
or 1/4" for patio doors
larger than 20 sq.ft.,
unit is out-of-square.
LEVEL INDICATOR
Accurate measurements are essential in determining level and plumb.
Most carpenters' levels have several bubble level indicators, making it
possible to measure all parts of the patio door.
Examine the horizontal indicator. If the bubble is centered between the
lines of the indicator, it is level.
If the bubble is not exactly centered, measure how far “out of level” or
“out of plumb” by maneuvering the end of the level until the bubble is
exactly centered. Measure the farthest gap between the level and the
surface. On a 2' level, the gap must not exceed 1/16", or on a 4' level (or
longer), the gap must not exceed 1/8", or the surface is out of
level/plumb.

• Proper installation is essential for keeping patio doors operating smoothly. If a patio door fails to operate properly, an inspection is necessary to
determine if it was installed correctly.
• A contractor or installer can assist in determining the cause of a patio door being “out of specication” and possibly correct it. Patio door problems due
to improper installation are usually not covered by the manufacturer’s warranty. For installation instructions, contact us or your supplier.
• The specications and measurements referenced in this guide are taken from ASTM E2112 Standard Practice for Installation of Exterior Windows, Doors
and Skylights.
Note: These instructions do not address inspection for proper “water tightness” or ashing. A “water tight” inspection requires removal of the exterior
siding around the patio door. Seek professional assistance regarding this issue.
