STEP 17: Tighten the Top Slider set screw
Once your Door Assembly is in place, you will
have access to the Top Slider Set Screw on the
side facing your sliding glass door. Tighten the set
screw using the 1/8” Allen Wrench. This will lock
the Top Slider in place.
STEP 18: Insert Rectangular Hole Plug if you are NOT using the Universal Lock
Assembly
If you choose not to use the Universal Lock Assembly, install the Rectangular Hole Plug in the lock cavity
on the open side of the assembled door panel. This will allow you to apply weather stripping over the
cavity. If you will be installing the Universal Lock, skip this step and proceed to Step 19.
INSTALLING THE UNIVERSAL LOCK ASSEMBLY
The universal lock assembly allows you to quickly lock your sliding glass door with the patio pet door
installed. It requires that you drill 2 small holes in the edge of your sliding glass door.
