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-82with “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.

FIG. 11: MOUNTING THE DM-62 MAGNET BODY HOUSING

MOUNT DUAL MAGNET BODY HOUSING FIRST

(1)LOCATE CENTER POINT BETWEEN DOORS

(2)MEASURE BACK ON STOP, 7/8" (22 mm) FROM DOOR CLOSE POINT (FRONT EDGE OF STOP)

(3)DRAW PENCIL LINE ON DOOR STOP, PARALLEL

TO STOP BUT 7/8" (22 mm) SET BACK FROM

FRONT EDGE

(4)ONE PERSON SHOULD HOLD MAGNET BODY ON STOP SO THAT FRONT HOUSING EDGE

LINES UP WITH PENCIL LINE

(5) INSURE MAGNET BODY HOUSING IS SQUARE TO PENCIL LINE

(6) SECOND PERSON SHOULD CENTER PUNCH EIGHT MAGNET MOUNTING HOLES THROUGH THE

HOUSING WHILE IT IS BEING HELD BY FIRST PERSON

(7)BEFORE DRILLING MAGNET MOUNTING AND WIRE WAY HOLES, CAREFULLY, CHECK THE SPACING BETWEEN THEM BY

REFERRING TO THE DIAGRAM SUPPLIED WITH THE PRODUCT

(8)MOUNT BLIND NUTS AND MAGNET BODY USING PROCEDURES CALLED OUT IN SECTION 2.3.2

2.5.6STEEL 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.
