3.5 MOUNTING THE SUB-PLATE
Note that for packaging security, the magnet body is affixed to the sub-plate. You must remove
it so as to reveal all the screw holes necessary for sub-plate mounting. Using the template, you
should have previously marked and drilled mounting holes for the sub-plate. You have been
supplied with an array of fasteners and because doors and stops will vary, the selection of
fasteners will vary from installation to installation. These fastener alternatives include machine
screw/blind nut combinations. You may not be familiar with blind nuts which are employed
with a number of Securitron products. They will work on any thickness metal header and are
used as follows: A 3/8" (9.5 mm) hole is drilled following the template for each nut. The nut is
then pressed up into the hole and lightly seated with a hammer tap. The nut is then collapsed
inside the header. A special collapsing tool is also included with each iMXD. For its use, see
Figure 3. Machine screws into blind nuts are much stronger than sheet metal screws so they
should be used for primary mounting with the sheet metal screws in a “helping” role. Also, note
that the hole preparation on the sub-plate allows for the use of flat head or socket cap screws
without the need for any washers.

3.6 MOUNTING THE MAGNET BODY AND COVER TO THE SUB-PLATE
As you prepare to re-mount the magnet body to the sub-plate,
note that the cable runs along the milled slot and then exits into
the space between the sub-plate and cover. Drill a wireway
hole to pull the cable into the frame anywhere on or near the
sub-plate slot. Then mount the magnet body utilizing the same
mounting hardware that you earlier removed.
Next, test the installation. Make sure that the strike plate
comfortably contacts the magnet face as the door closes. If it
does not, the outward projection of the strike plate should be
adjusted by adding or subtracting rubber washers. Finally, the
