3. DOOR HINGE INSTALLATION
If you are replacing a door and the hinge recesses exist on the
LOCATING THE DESIRED DOOR HINGE LOCATIONS
door jam, there are 2 methods of determining where to cut the
recesses out on the door.
• Method #1 - Measure the hinge locations of the previously used
door from the top of the door down (do not measure from the bot-
tom up since this may create a large gap at the top of the door).
• Method #2 - Measure the distance from the top of the door jam
down to the first hinge and subtract 1/8 in. This will create a 1/8 in.
clearance gap at the top of the door.
If the door jam that you are installing the door into does not have
hinges or hinge recesses, mark the center of the hinge locations
on the edge of the door. This centering mark will be used in step 2
to locate the Hinge Template.
• Determine which way the door will open and how the hinges will
MAKING DOOR HINGE RECESS
need to be positioned for proper operation. Locate the Hinge
Template on the edge of the door such that the hole lines up with
the mark scribed in step one (the center of the hinge).
Installation tip: With a pencil, outline the inside of the Hinge
Template, this is the area that will be chiseled out. Remove the
template and position the hinge inside the pencil lines to verify the
door will open as desired.
• With the Hinge Template in
place, insert a screw into the
hole, and fasten the template
onto the door. With the template
fastened to the door, use a chisel
to remove the material inside the
template as shown. Remove the
template and chisel out material
left behind at the template screw
location. Screw the hinges onto
the door.
