Below are some of the most common problems
faced when installing DOUBLE DOORS
Troubleshooting tips for installing double door and all
Prehung units
when installing prehung units particularly double
door units; there are certain problems that may arise.
Generally, the larger the opening, the more likely it is
to be out of square. When installing units into an
existing opening, it may not be sufficient enough to
align the jambs with the existing framing. If the
existing framing is out of square and the prehung unit
is aligned with the existing framing, then the prehung
unit will also be out of square. Problems with
alignment can happen with any prehung unit but
the problems are enhanced with double door units
due to the extra door.
Here are some solutions to the common problems of
installing double door units. These solutions can also
be used with other prehung units.
Problem No. 1: Doors don’t align at top
SOLUTIONS
Shim at Points A, B and, or C. If there is sufficient
spacing on the opposite sides of point A and B
then shim at points A and B to shift frame and
align doors at top and bottom. If there isn’t, shim
at point C to lift up side and align doors
