centerline in the door frame,
make sure the door is closed properly
(against the stop in the
case of a single acting door or in centered rest position in the case of a double acting door).
Note that the door closer may need adjustment particularly in the case of a double acting door.
Then, using a pencil, trace the edges of the door on the frame indicating precisely how the door
lines up under or adjacent to the frame. Measure the distance between the two “door lines” and
set your magnet body mounting center line in the middle of these two lines. Next, you are ready
to identify the correct template and prepare the frame to receive the magnet body.
The techniques to employ depend on the type of door frame and the next three Sections cover
respectively
hollow aluminum, steel and wood
. Each Section assumes that you will prepare
the door frame to accept the magnet (when it has not been prepped in advance by the door
manufacturer). Note that
a multi use template
has been supplied for frame preparation
depending on the frame type (discussed in the following three sections).
2.2.1 HOLLOW ALUMINUM DOOR FRAME MOUNTING (STOREFRONT TYPE)
Following the template, a rectangular slot must be cut into the door frame. This can be done
with a router or sabre saw. The slot should straddle the center line and be positioned close to
the edge of the frame opposite from the hinges in the case of horizontal mounting to maintain
security (the closer the lock is to the hinge side of the door, the more leverage is exerted on it
when an attempt is made to open the door). However, when you determine where you will
position the magnet body,
be sure that the strike will go into the adjacent area of the door
without encountering an obstacle (such as a door adjustment screw) that will interfere with
mounting the strike. Then three holes must be drilled on each end of the cut-out following the
template.
To actually mount the magnet
once the frame has been
prepared, note that it is not
handed and it doesn’t make
any difference which end the
wire exits from. You will be
first attaching supplied “flush
mount brackets” to the frame
oriented as shown in the
drawing to the right by using
supplied flathead screws and
the six holes you have drilled.
The flush mount brackets
together with the supplied shim plates allow you to set the plane (level) of the magnet face to
the frame surface. The
magnet face should protrude about 1/16” (1.5 MM) beyond the
frame surface
. To achieve this, the flush mount brackets are oriented as shown in the drawing
above and you will add one shim plate each. Then the magnet body is attached to the flush
mount brackets via four supplied flathead screws.
Be sure to apply the supplied threadlock
to all mounting machine screw threads.
2.2.2 HOLLOW METAL DOOR FRAME MOUNTING (16 GAUGE)
Following the template, a rectangular slot must be cut into the door frame. This can be done
with a router or sabre saw. The slot should straddle the center line and be positioned close to
the edge of the frame opposite from the hinges in the case of horizontal mounting to maintain
security. Also three holes must be drilled on each end of the cut-out following the template.
Note that some hollow metal (steel) door frames are filled with concrete. This makes the
installation more difficult (for this type of frame, it’s optimum if the frame is prepared in advance
