2.5 MOUNTING PROCEDURES FOR SPECIFIC DOOR TYPES
2.5.1 ALUMI NUM FRAME GL AS S DOOR M OUNTING
This is a common door type that utilizes the Magnalock. Certain mounting problems can arise
depending on the configuration of the door and frame. Often, the header is not wide enough
for the depth of the magnet. This can mean that none of the mounting screws can be run into
the header or that in t he case of t he model 62 and 82, on ly two of t he four will fit . Another
aspect of the mounting screw problem is that the screws might line up with the end of the
header extrus ion. Als o the wires may exit beyon d t he end of th e h eader so th at they will b e
exposed and vulnerable to tampering.
Most of the problems ar e solved by t he use of Securitron 's Universal Header Brack et (part #
UHB-CL or UHB-BK). This bracket will function with the m odel 32, model 34 or model 62
Magnalock. A separate version (UHB-82) is offered for use with the longer model 82. The UHB
extends the depth of the header either 1" (25mm) or 1 1/2" (38mm) depending on which way
it's oriented. This usually allows mounting of all screws and since the bracket is itself a hollow
extrusion, the wire is run inside the bracket and therefore is hidden. Even with use of the
bracket, it is p ossib l e th at on e set of m oun t ing sc rews may l in e up with th e en d of t h e h ead er
when the m odel 62 or 82 is us ed. To deal wit h t h is situ at ion, some ad ju st men t of t h e m agn et
mounting position is possible. Instead of the two rubber washers supplied with the strike, one
or three may b e used . If th e door is s ecured onl y by t he Magn alock (th ere is no mechan ical
swingbolt) the door closed position may be altered to allow all mounting screws to be used.
Finally note t hat a mod el 62 ins tal l ation on th is t yp e of d oor is ac cep tab l e if on l y two m oun t ing
screws are used. Since the screws run into steel nuts, the fastening technique is very strong.
It is best to use all four screws, but particularly on this type of door, which is inherently not high
security (the glass may be shattered for forced entry) firml y mou n ting two screws is acceptable.
Aluminum frame headers typicall y employ a “blade” st op which is far t oo thin to provid e a
mountin g su rfac e for t h e mag net . Not e th at Fig u re 4 sh ows t he Mag net mou n tin g on t h e door
stop. Accordingly, on aluminum frame glass doors, the magnet body mounts directly onto the
header. This c an be accompl is h ed by cu t ting away a sect ion of the b l ade stop. Th is techn ique
is preferred in th at the p rojection of the m agnet in to the op ening is minimized . An altern ate
