After establishing the position for the mounting of the lock/TJ-Bracket, use Figure 4 above and
the following step-by-step installation sequence to mount the lock onto the door frame/header.
(The TJ-Bracket may be used as a template to mark the required mounting hole locations).
After marking the desired mounting holes on the door frame mounting surface, center punch
these locations, and then:
For Metal Door Frame/Header: Drill 3/8” [9.5mm] diameter holes through the door frame at
each location and install blind nuts (Item #4) into the 3/8” [9.5mm] diameter holes in the door
frame as follows:
a.
Using the blind nut collapsing tool provided (with blind nut in place), insert the end of the
blind nut into the hole.
b.
Using a hammer (if necessary) tap the nut in until the upper lip seats against the door frame
surface.
c.
While holding the hex portion of the collapsing tool with a 1/2” box-end wrench or vise grip
pliers, turn the socket head cap screw of the tool using a 3/16” hex wrench. Note: Maintain
firm pressure toward the door frame mounting surface while collapsing the nut.
d.
Once the blind nut is adequately collapsed, remove the tool from the nut by backing the cap
screw out of the blind nut thread.
e.
Install each successive blind nut onto the collapsing tool (cap screw) and repeat steps a
through d above until all desired blind nuts have been installed.
For Wood Door Frame/Header:
If using #12 X 1-1/2” long screws (Item #1): Drill 3/16” [4.8mm] diameter holes X 1-1/4”
[31.8mm] deep (minimum) into the door frame at each of these locations.
If using #14 X 4” long screws (Item #2): Drill 7/32” [5.5mm] diameter holes X 3-3/4”
[95.3mm] deep (minimum) into the door frame at each of these locations.
Place the TJ-Bracket onto the frame mounting surface aligning the holes in the bracket with
the previously installed blind nuts (for metal frame) or drilled holes (for wood frame). Using
a #3 Phillips screwdriver, secure the bracket to the frame with:
For Metal Door Frame/Header: Use 1/4-20 X 1-1/2” long Phillips flat head screws (Item
#3) provided.
For Wood Door Frame/Header: Use #12 X 1-1/2” long Phillips flat head type “A” screws
(Item #1) or #14 X 4” long Phillips flat head type “A” screws (Item #2) provided.
Establish location then drill a 3/8” [9.5mm] diameter hole through the door frame for the lock
power cable. Note: This hole must be positioned within the large slotted “window” in the
back of the TJ-Bracket when the bracket is installed on the frame mounting surface.
Remove the standard mounting bracket (originally included with the lock) from the top of the
lock housing as follows:
a.
Using a #1 Phillips screwdriver, remove the 8-32 flat head screw holding the lock housing
front cover in place. Remove cover and set aside the screw and cover for later assembly.
b.
Using a 1/16” hex wrench, back the two (2) 6-32 socket set screws out far enough to
disengage the mounting bracket. Note: It is not necessary to completely remove the set
screws – five (5) 360-degree counterclockwise turns is normally far enough.
c.
Slide the bracket to disengage from the top of the lock housing. Note: The bracket/lock
interface can be disengaged by sliding the lock (or bracket) 1” to 2” laterally to one side
or the other, then withdrawing away vertically – sliding the lock or bracket the full length
of the housing to remove or install is not necessary.
Assemble the lock housing to the TJ-Bracket by engaging the top of the lock with the bracket
and sliding the lock into position (centered on the bracket). Tighten the two (2) 6-32 socket
set screws using a 1/16” hex wrench to secure the assembly.
After all electrical wiring has been completed, install the housing front cover and fasten in
place using the 8-32 flat head screw (previously removed).
