2.5.4 DOUBLE DOOR MOUNTING
Several possibilities exist for this application. In some cases, one of the door leaves is pinned
so that only one leaf is used and this is secured by a single Magnalock. If both leaves are to be
active, two Magnalocks can be used. For the most attractive installation, they should be butted
together but if obstructions exist in the header that interfere with mounting, the magnets can be
separated somewhat. Another possibility is to use Securitron's split strike which is available for
the model 62 and model 82 (use of a split strike with the model 32 or 34 series would provide
inadequate security) In this method, a single Magnalock is mounted in the center of the header
and a half size strike is mounted on each leaf. This reduces the holding force to about 550 lbs.
(250 KG) for each leaf with the model 62 and about 850 lbs. (385 KG) for each leaf with the
model 82. The split strike (part number ASS-62 or ASS-82 with “M” suffix for metric) is
available either as part of a complete Magnalock or supplied separately as a replacement for the
standard strike. Read section 2.7 for information on Dress Covers which improve the
appearance of a double door installation. Certain electronic considerations also apply when
Magnalocks are used on double doors. See section 3.5.4.
2.5.5 DM-62 DOUBLE 62 LOCK
This is a special order lock which provides two Model 62’s in a single, stainless steel housing. It
is intended for mounting on any double door with no center mullion. The advantage of this
product is solely in its esthetic appearance. Mounting procedures are somewhat different from
the standard Magnalock. As Figure 11 shows, the magnet body housing mounts first. When
this has been accomplished locate the center points for mounting the two strike plates by
measuring in 4” (102 mm) from the housing end. Then, simply use the supplied strike templates
on the doors, making sure to drop the top edge of each strike about 1/10” below the point at
which the door stop meets the door. Note that on certain door types, spacing brackets may be
employed as with single Magnalocks.

2.5.6 STEEL HEADER FILLED WITH CONCRETE OR WOOD FRAME MOUNTING
Securitron offers a combined bracket in three versions to suit the three Magnalock families. The
part number of the “Concrete/Wood Bracket” is CWB-32, CWB-62 or CWB-82. Two finishes
are available (suffix CL or BK) and for metric locks, the brackets include the suffix “M”. Note
that the CWB bracket is not offered with the model 34. It’s functions are accomplished by the
UMB bracket for the model 34.
