special procedure: Apply Threadlock onto the strike mounting screw threads and insert the
screw into the MXD sex bolt turning in to catch a few threads; pull on the strike plate to
compress the spring exposing the shaft; using a vise grip pliers set, hold the shaft on the two
flat areas provided while tightening the strike assembly; turn the strike mounting screw a couple
of more turns and then re-rotate the strike so that its roll pins again insert into their bushings;
finish by tightening the strike mounting screw. Do not over-tighten the rubber washers.
FIG. 1: STRIKE PLATE MOUNTING ASSEMBLY
2.5 MOUNTING 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. Note the following points,
however: 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. Review
the section on magnet mounting in your Magnalock manual to see how to mount and collapse
the blind nuts. 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.
2.6 MOUNTING THE MAGNET BODY AND COVER
As you prepare to mount the magnet body, 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 1 3/4” (model 32) or 2 1/2” (model 62) socket cap machine screws supplied with the
housing together with the washers. Don’t use the machine screws supplied with the
Magnalocks as they are too long. Do use the gold washers (furnished with the Magnalock
hardware pack) under the heads of the socket cap screws which mount the magnet body.
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. Next, verify that the door smoothly
opens and recloses the roughly one inch of movement that is permitted by the spring
loaded sex bolt. If the sex bolt appears to “drag”, the door and frame/header may be out of
square as can be the case with older buildings. This situation can be alleviated by slightly
loosening the magnet mounting screws which gives the magnet some ability to “tip” back into a
square condition. Alternately, shims may be placed under the appropriate edge of the sub-plate
to square up the installation.
