or right hand doors but be sure that the edge of the template is flush to the corner of the door
frame stop for best mounted appearance.
The template will indicate the positions of the holes location as well as the holes diameters. This
depends on which Magnalock type is being used. Note that if the door stop is narrow, you
may need to add a filler plate to create a wide enough mounting surface for the sub-plate.
2.2 TEMPLATE USE ON AN ALUMINUM FRAME GLASS DOOR WITH BLADE STOP
A blade stop is so narrow (around 1/8”) that nothing can be mounted on it. You cannot place
the folded edge of the template in the corner made by the stop and door surface as you will not
be mounting on the stop. You will be mounting the sub-plate adjacent to the stop directly on
the frame extrusion. To use the template, cut it with a scissors along the fold line. To mark the
strike plate/permanent magnet bracket holes, open the door slightly and insert the template
behind the blade stop until it just touches the door frame. Allow the door to fully close to
capture the template. Accurately punch your mounting holes for the strike plate/permanent
magnet bracket just as if the blade stop was not present.
To mark the holes for the sub-plate, you will use the other half of the template. Measure the
distance from the door surface to the surface of the blade stop and “subtract” that distance from
the template half by either cutting the template or re-folding it. The distance is usually around
3/8” (9.5MM) but it will vary from door to door depending on the thickness of the blade stop and
the spatial point at which the door is closed.
An alternate method for mounting the sub-plate dispenses with the template half and uses the
sub-plate as its own template. To employ this method, close the door and measure back at each
end of the bracket area, from the surface of the door past the blade stop 5/8” (16MM) for a
model 32 Lock or 9/16” (14MM) for a model 62 Lock. Draw a line between the two points.
Align the front edge of the sub-plate to this line to achieved the correct backset. To set
the lateral position of the sub-plate, move it away from the frame corner about 1/8” (3MM).
This will allow the housing cover clearance. Mark and drill the mounting holes for the sub-plate.
2.3 IF THE DOOR IS THINNER OR THICKER THAN STANDARD
The MXD sex bolt is dimensioned to precisely fit a 1 3/4” (44.5 MM) thick door which is a
common size. If the door is a different thickness, contact the factory. Securitron can supply
washers for a thinner door, which go under the head assembly. For thicker doors, the bolt may
be partially unscrewed to expand it for use with up to a 2” thick (51MM) door. If you do this, be
sure to apply Threadlock provided on the threads. When the bolt is “expanded” to suit a thicker
door movement is proportionately reduced. The factory can supply spacers to adapt the bolt to
thicker doors while retaining full door movement distance.
2.4 MOUNTING THE PERMANENT MAGNET BRACKET, MXD SEX BOLT AND STRIKE
Note the assembly drawing in Figure 1: After all the holes are drilled from the template is to
install the permanent magnet bracket. The model 62 version comes with four self tapping
screws to hold the bracket to the door and the model 32 version comes with two. Note that this
bracket is not handed. It can be flipped to place the permanent magnet either to the right or
the left to line up with the proximity switch array on the sub-plate. The proximity switch
array can also be transferred to either side of the sub-plate for flexibility to maximize
wiring options. In the case of a concrete filled header, for example, the cable can not usually
be pulled up into the header. A flex conduit fitting can be attached to either end of the cover
and the proximity switch array and permanent magnet pack would then be positioned on the
opposite side of the fitting. Mount the MXD sex bolt. The sex bolt includes two pins under the
head which will go in two separately drilled holes for anti-rotation. The pins act as their own
template. Unscrew the threaded base plate of the bolt and insert the bolt into the 1” hole which
you should have previously drilled. Lightly tap the head and the pins to mark the door. Remove
the bolt and drill 1/8” (3.2mm) diameter holes for these anti-rotation pins. Reinstall the sex bolt
head, apply Threadlock on the sex bolt base plate threads and screw on tightly. Install the roll
pin bushings into the prepared holes and install the long (2”) roll pins into the strike plate. Do
not use the shorter roll pins delivered with the Magnalock. Then, place the flathead strike
mounting screw through its plastic bushing and through the strike plate. On the other side of
the plate, push three rubber washers then one steel washer onto the strike mounting screw as
shown in Figure 1. To screw this complete assembly into the MXD sex bolt, you have to follow a
