 Drill one 3/8” [9.5mm] diameter hole through the Z-Bracket at the center (strike mounting)
hole.
 Drill two (2) 1/2” [12.7mm] diameter holes through the Z-Bracket at the marks to each side
of the center hole.
Door Position Actuator Installation: For locks that include the “D” (Door Position) option,
install the actuator block by performing the following:
a. After marking the mounting holes for the actuator block (Item #12) on the Z-Bracket using
the mounting template provided with the lock (or upgrade kit), center punch these locations.
b. Drill two (2) 1/8” [3.2mm] diameter holes through the Z-Bracket at the center punched
locations.
c. Using a #1 Phillips screwdriver secure the actuator block to the Z-Bracket with the two (2)
#6 X 3/4” long Phillips pan head type “A” screws (Item #13) provided. Note: Make sure
that the arrow of the label on the backside of the block is facing toward the mounting
edge of the lock.
If a field upgrade to the “D” version is being performed, please use the installation template
(P/N 500-61050) included with the upgrade kit to install the switch inside the front cover. (See
the installation and operating instruction manual included with the lock for electrical
specifications of the switch).
 Reinstall the Z-Bracket to the door using the two (2) #14 X 1-1/4” long slotted hex head type
“A” screws (Item #5).
 Insert the 5/16-18 X 1-1/2” long socket head cap screw (Item #6) through the center Z-
Bracket mounting hole and into the door.
 Start the sex bolt into the 1/2” [12.7mm] diameter hole from the opposite side of the door.
Do not fully seat the sex bolt against the surface of the door at this time, but thread the sex
bolt onto the end of the mounting screw. Using a 1/4” hex wrench, continue to thread the
mounting screw into the sex bolt while ensuring that the assembly maintains a straight
(perpendicular) alignment to the door.
 Using a hammer and the 1/4” hex wrench, gradually tighten the screw into the sex bolt until
it is snug, and then tap the head of the sex bolt toward the face of the door. Keep repeating
this procedure to slowly “walk” the sex bolt into place (head against door face) – this ensures
a straight (perpendicular) alignment of the sex bolt to the door.
 Insert the two (2) strike roll pin bushings into the 1/2” [12.7mm] diameter holes in the Z-
Bracket (See Figure 5). Note: The roll pin bushings will need to be cut to the same
thickness as the Z-Bracket. This is required so that the bushings do not extend beyond the
surface of the Z-Bracket and interfere with the Dress Cover installation.
 Insert the plastic strike mounting bushing and the 5/16-18 X 1” long socket flat head screw
(Item #7) through the center hole of the strike.
 Install two (2) of the neoprene washers (Item #8) over the screw on the opposite side (roll
pin hole side) of the strike.
 Holding the T-Nut (Item #9) into the center hole on the back side of the Z-Bracket, position
the strike to the front side of the bracket. Insert and thread the 5/16-18 socket flat head
screw (Item #7) into the T-Nut.
 Using a 3/16” hex wrench, lightly tighten the assembly to snug.
 Verify proper spacing relationship between face of lock (magnet) and strike plate. The face
of the strike should contact the face of the lock when the door is closed. Note: A total of
four (4) washers (Item #8) are provided (between the original lock hardware pack and the
one in this kit). Note: Usually 2-3 washers are adequate to provide correct spacing, and
washers may be added or removed as necessary to create proper fit, but at least one (1)
washer must be installed between the strike and Z-Bracket.
