Here's how the manual 4-way locking mechanism works:
- In Only: The dog can come in but cannot go out again (e.g., once the dog is in for the night, owner can make sure he stays put).
- Out Only: The dog can go out but cannot come in again (e.g., the owner does not have to find the dog to put him out – the dog can go out when he's ready).
- Locked: The dog cannot come in nor go out (e.g., the owner is gone for extended periods of time).
- Unlocked: The dog can enter or leave as desired.
Training your dog to use your dog Door: Most dogs will learn to use the pet door quickly. However, there are a few which may be a little anxious at first. Be patient with your dog. Don't force him through the flap or he may become frightened. Once you have installed your dog door leave it propped open for some time. Let your dog become familiar with it and go in and out freely. Establish a motive, such as a food reward, for your dog to use the door. First, feed your pet near the door, inside and then outside. Do not to use the lock on your pet door until your dog is thoroughly familiar with using the door.

Instructions for installing the Pet Door:
Measuring and marking:
- Measure the height of your dog at the abdomen (belly).
- Mark this measurement on the outside of your door and draw a straight horizontal line.
For wooden doors, panels and screens:
 1. Place template in marked position on door and draw completely around.
 2. Cut out hole. This may be done by drilling a hole, and then using an electric jig saw to cut along the inside of the drawn line. Be careful to cut hole square to the door, particularly with thicker doors. For screen doors, use scissors or a sharp knife to cut the hole.
 3. If necessary, cut interior frame with a sharp knife to correct length to suit your door panel. Take care to keep hands clear of the blade, and support inside of molding with a suitable piece of wood.
 4. Position interior frame on inside of door and mark 4 screw positions. |
For panels less than 7/8" (22mm) thick: remove interior frame and drill screw clearance holes in panel to approximately 1/4" (6mm) diameter. Using the appropriate screws and working from the inside of the house, tighten the interior frame to the exterior frame. Use the screws as follows:
| Panel Thickness |
Screw Length |
| 0-1/8" (0-4mm) |
1/2" (13mm) |
| 1/8" – 3/8" (4-10mm) |
3/4" (19mm) |
| 3/8" – 5/8" (10-16mm) |
1" (25"mm) (not supplied) |
| 5/8" – 7/8" (16-22mm) |
1-1/4" (32mm) |
For panels thicker than 7/8" (22mm), do not drill screw clearance holes. Instead, first screw interior frame to inside of panel with short (1/2" (13mm) screws. Drill out the 4 screw holes in the exterior frame to allow close clearance on screw. (Recommended drill bit 3/16" (4.5mm) diameter.) Fix exterior frame to exterior of door using 3/4" (19mm) screws. When installation is complete cover screw heads with caps supplied.
 Walls: After making a hole in your wall, line with 3/4" (19mm) plywood or similar material. This gives a heat tunnel to the installation and readily accepts the sizing screws. After construction of tunnel, proceed to step 4 above.
Glass: It is recommended that you ask a glazier to cut a hole of 8-3/4" (223mm) diameter in the position required, and then install the dog flap as detailed at instruction 3 and 4 above.
Note: Not for double-glazed, toughened or tempered glass applications. Tempered glass usually has an indicia mark in one corner. If you see this mark, it is tempered glass. Homes built after 1985 are more likely to have tempered glass. Dual-pane, insulated glass units are almost certainly tempered and should not be cut into. The best way to put a pet door in tempered, double-glazed, or toughened glass is to have a new piece of glass made for you by a local glass shop with a hole pre-cut in the glass.
