5.2.2.1. Lock Installation
Using Figure 3 (for metal door frames) or Figure 4 (for wood door frames) above, the
template provided and the following step-by-step installation instructions, complete the
installation of the lock onto the door frame.

1. Locate the two (2) marks applied to the door frame for the mounting bracket

using the template in the previous strike installation section (Section 5.2.1.1,
Step 1), then:

a. For Metal Door Frame: Drill two (2) 3/8” [9.5mm] diameter holes

through the door frame at these locations.

i. Install blind nuts (Item #11) into the 3/8” [9.5mm] diameter

holes in the door frame as follows:

1. Using blind nut collapsing tool provided (with blind nut in

place), insert the end of the blind nut into the hole.

2. Using a hammer (if necessary) tap the nut in until the upper

lip seats against the door frame surface.

3. 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.

4. Once the blind nut is adequately collapsed, remove the tool

from the nut by backing the cap screw out of the blind nut
thread.

5. Install the second blind nut onto the collapsing tool (cap

screw) and repeat sub-steps i1 through i4.

b. For Wood Door Frame: Drill two (2) 3/16” [4.8mm] diameter holes X 1-

1/4” [31.8mm] deep (minimum) into the door frame at these locations.

2. Remove the mounting bracket (Item #12) from the top (dovetail) area of the

lock housing as follows:

a. Using a #1 Phillips screwdriver, remove the 8-32 UNC flat head screw

(Item #8) holding the lock housing front cover (Item #9) in place.

Remove cover and set screw and cover aside for later assembly.

b. Using a 1/16” hex wrench, back the two (2) 6-32 UNC socket set screws

(Item #10) out far enough to allow free (sliding) movement of the
mounting bracket. Note: It is not necessary to completely remove the
set screws to allow removal of the bracket – five (5) 360-degree

counterclockwise turns is normally far enough.

c. Slide the bracket far enough to disengage the bracket from the top of the

lock housing. Note: The bracket/lock interface can be disengaged by
moving the lock (or bracket) 1” to 2” [25-50mm] laterally to one side or
the other, then withdrawing away vertically – you do not have to slide the

lock or bracket the full length of the housing to remove or install.

3. Place the mounting bracket onto the frame aligning the two (2) slotted holes in

the bracket with the previously installed blind nuts (for metal frame) or drilled
holes (for wood frame). Using a #3 Phillips screwdriver, lightly secure the

mounting bracket to the frame with:
