Product : BIGWING Style Pet Flap Lockable 4 Way Locking Cat Door Brown L
3 steps to install: Step 1. Identify the installation position of the cat door on your house door. When looking for the position, you need to estimate the height (average installation height is around 10-15 cm from the floor) for your pet to go through the hole. With the help of a ruler, run a pencil around the edge of the paper film of the frame where it would touch the door. You need to make a legible line as this will be used for cutting against. Mark the four screw holes on the house door (shows on the paper film).
Step 2. Before cutting the tunnel hole, choose the dotted lines on four corners, then drill holes in all the corners with 12mm drill. After that use a electric saw to cut your house door along the dotted line, until the tunnel hole drops out from the door.
Step 3. Before installing the cat door,check the actual position by comparing with the cat door and for drilling holes. After that, you can install the cat door on the tunnel hole and tighten the 4 screws. (If your door is a glass door, use glass cutting tools, cut it out and fix it with the glass glue.)
