PROPER DOOR INSTALLATION
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 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4'level(orlonger),thegapmustnotexceed1/4",orthe

Proper installation is essential for keeping doors operating smoothly. If a 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 door being “out of specication” and possibly correct it. Door problems due to •
improper installation are usually not covered by the manufacturer’s warranty. For installation instructions, contact us or your supplier.
The specications 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 where the product integrates with the structure. A “water
tight” inspection requires removal of the exterior siding and interior trim around the door. Seek professional assistance regarding this issue.
