READ THOROUGHLY BEFORE INSTALLING  REV#0001A 
 
Note

: 

For in-swing (hinge side) door mounting the TJ bracket and hardware kit is required

. 

Refer to Mounting 

Instructions for TJ1107.

IMPORTANT: Always handle electro-magnets and armatures carefully. The mating surfaces have been carefully 
manufactured to provide maximum holding power. Mating surface damage can significantly reduce holding power. 

Before starting, make s ure t he c orrect  drill template  is  available f or the t ype of  installation  planned. Door   swing and 

construction, d oor frame  mat erial an d c onfiguration m ust  be co nsidered before  d eciding o n th e pr oper mo unting  kit and  

method. See the Application Bulletins below for di agrams of typical door configurations and part numb ers for spacers, shims 

and mounting brackets required for each type of installation.  
The 1107xD Series Electro-magnet mounts firmly and rigidly to the underside of the header on the stop side of the door, while 

the armature mounts to th e face of the  door with special hardware that allows enough movement so that the  armature can 

align itself to the magnet face for maximum effectiveness even if it is not perfectly parallel and/or square.  
A 2-1/8” wide flat surface is required to mount the 1107xD series magnet (see Figure 1).  
For installations involving drilling and tapping of hollow metal door frames, the material thickness should be at least 1/8”. Sheet 

metal screws may be used for wood frames and cl ad frames. For thinly clad d oors or  wooden doors without sufficient solid 

backing, a reinforcing plate may be required. See Figure 3.   

STEP 1)   MARK AND DRILL JAMB HEADER & INSTALL THE MAGNET MOUNTING PLATE 

It is al ways  a goo d ide a to h old the com plete assembl y i n place  

before drilling to mak e sure the placement does not  interfere with 

door operators or coordinators. Magnetic locks should be mounted 

as close to the latch s ide of t he door as  is practical for m aximum 

leverage. 
Use the s upplied tem plate t o mark the  door a nd th e j amb for  

drilling.  Depen ding on the ma terial, size the  drill bit for either #1 0 

Sheet Metal screws or for ta pping 10-32

machine screws.

 Do not 

prep jamb for the (2) # 10 locking screws at this time

Use star  washers (included) with the scre ws to prevent l oosening 

over time. T he four mounti ng scr ews s eat i n the slotted  pocket 

holes of the mounti ng plate ( Figure 2). Inst all the scr ews, but do  

not tighten ful ly to all ow for  adjustme nt after the armature has  

been mounted to ensure proper alignment. If a standard filler plate 

is used (Figure D Page 6), the mounting plate should be attached 

directly to the filler plate using the pre-tapped holes, and clearance 

hole for wiring. 

If a – 

W (wide) filler plate

 is used, the mounting plate should be attached directly to the filler plate using the pre-tapped holes, 

and clearance hole for wiring. Eliminate any sharp edges that could damage the wire insulation.
