STEP 19: Insert the Door Lock
Housing
Insert Door Lock Housing on the open side of
the assembled pet door panel so that the Lock
Arm is in the up position when open as shown
in Figure 15.
STEP 20: Install the Lock Knob
Install the Lock Handle so that the handle is
vertical when the lock is open (Lock Arm is in up
position.) and so that one of the detents in the
Lock Handle shaft aligns with the Lock Arm Set
Screw. Turning the Lock Handle counter-
clockwise should move the Lock Arm to the
closed position. If the Lock Knob does not easily
insert into the Lock Arm, loosen the Lock Arm
Set Screw.
Note that there are (2) detents in the Lock Knob
for left and right opening door opening sliding
glass doors. Make sure the handle is oriented vertically and that one of the detents aligns with the Lock
Arm Set Screw.
STEP 21: Tighten the Lock Arm set screw
Tighten the Lock Arm set screw using the 1/16” Allen wrench
provided. Note that there should be a sight gap between the Lock
Knob and the patio pet door panel when the unit is assembled
correctly.
