For height align-
ment, close the door
until the latch makes
contact with the door
jamb. Use a pencil
and mark the top
and bottom of the
latch.
Use a combination square and transfer the
lines on the front edge of the door to the side.
This will show the location of the latch when
it is in the locked position.
Find the center line of the jamb. This
example shows the center line on a 4” wide
offset hung door. The center line is 7/8” from
the stop, or one half the thickness of the
door. Use a combination square and draw a
vertical line at this point.
