Door Installation Guide
1. Verify that the rough opening (r/o) is at least ½” wider on all sides of the outside of
the jamb. If the opening is less than ½”, it may be fine for the installation if the r/o is
square and plumb.
2. Make sure the framing surrounding the door is solid and free of movement. If the
walls surrounding the door are not properly secured, this could allow for unwanted
movement of the door after it is installed in the r/o. This could result in damage of
the door unit.
3. Check the r/o for any security wires that may need to be installed into the jamb of the
door and the slab. Drill and install wires and contacts as necessary.
4. Check the height of the finished floor in relation to where the sweep on the door slab
will be. It may be necessary to raise the area under where the threshold of the door
will rest. Keep in mind any rugs or floor coverings the customer is considering
placing at the interior entrance area of the door and allow for clearance of the door
slab and the sweep.
5. Place the door jamb,
or frame, in the r/o.
Make sure the
threshold portion of
the frame is resting
completely flat on the
subfloor and that no
debris is under the
jamb.

6. After making sure the jamb is plumb, mark on the studs or sheetrock where the
mounting flanges are and the bolt holes of the flanges (picture 2). It may be
necessary to remove the sheetrock behind the flanges so the bolts do not hinder the
ability to install casing on the inside after the door is installed (picture 3).
