Installation Instructions

Installation Instructions

Measure and Cut Wall Access

Before installing, ensure your pet will be able to use the door from the inside and the outside. Check for electrical wiring or pipes in the wall area. If you must, cut a small hole within the wall to verify if there are any studs, wiring, or plumbing.

1. Using a stud finder, find the edge of a stud. Draw a 5” vertical line on the edge of that stud about one foot off the floor.

2.Draw a horizontal line through a mark of the shoulder height of your pet.

3.Now, cut the template to the appropriate size (8 5/8” x 15 5/8”). Put the template against the wall, and align the shoulder height line on the template with the shoulder height line you drew on the wall. Make sure your template is on the EDGE of the stud, and not over it.

4. Trace the template to the wall with a pencil.

5. For Large Models, keep in mind you are cutting a hole from the inside edge of one stud to the inside edge of its neighboring stud. In common framing, this space should measure 14 ½”

6. Now, drill the four corners all the way through the wall, using a 5/16” drill bit. Make sure to keep the drill level with the wall.

7.With a jigsaw or another cutting device, cut the hole.
a. For Large Models, use the Inside of Frame A to check the fit. Don’t force anything. If the hole is too small, just remove the frame and re-cut or file the hole slightly to enlarge. Do not cut more than 1/8” from your previous cut. Once it fits, adjust the frame so it’s level and square.

8.Now, repeat the previous steps for the Outside frame. You can use the previously drilled holes as your corners. Check that your lines match, and measure frequently.

Installing the Supports

1.Measure the width from the inside of the outer wall to the inside of the inner wall.

2. Cut a block of 2” x 4” or 2” x 6” wood to 6” – 8” long for use as a support beam.

3.Remove any debris that may be inside the wall.

4.Place the support beam inside the wall so that the top is even with the bottom of the cut-outs.

5.Use 2 decking screws to attach the inner side of the support beam. Make sure it is flush with the bottom of the cut-outs.

6. Now, on the outside, use 2 decking screws to fasten the outer portion of the support beam. You might need to drill a hole through the siding slightly larger than the heads of the screw if you’re placing screws into vinyl siding.

7.If needed, repeat the process with a vertical length of 2” x 4” or 2” x 6”. This will become the vertical support that you will end us fastening the edge of the frame into.

Small Door Only

Attach the SmartDoor to the Wall Extension Frame A (Small Door)

1.Locate the Inside Frame A. It will have 6 screw cups along the outer edge.

2.Place the inside portion of your Electronic SmartDoor inside the frame.

3. Secure the SmartDoor to the Inside Frame A with a machine screw in each of the four corners. On the backside of the frame, add a lock washer and then tighten each of the 4 hex nuts.

Install the Assemblies into the Wall (Small Door)

1. Insert the SmartDoor assembly from Step 3 into the inside wall. The frame should be flush with the wall and level both vertically and horizontally.

2.Locate the Outside Frame B for outdoor placement. It should have 8 screw cups along the outer edge.

3.Beginning inside, install the 6 Phillips head wood screws and washers through Outside Frame A into your wall and the 2” x 4” or 2” x 6” support you installed earlier. Do not overtighten.

4.From the outside, install the 8 Phillips head wood screws and washers through Outside Frame B into wall and into the 2” x 4” or 2” x 6” support you installed earlier.

5.Use window caulking to fill in any seams and gaps in your installation.

6.Install the batteries. Your door is now ready! You can begin training your pet.

Large Door Only

Attach the SmartDoor to the Wall Extension Tunnel (Large Door)

1. Place the SmartDoor in the lip of the tunnel extension.

2. Tape the tunnel extension to the SmartDoor. The rear door frame of the SmartDoor won’t be used in the wall installation.

Install the Assemblies into the Wall

1. From outside, place the frame in the wall. Make sure the frame is level vertically and horizontally before putting in any screws.

2. Insert the SmartDoor and the Tunnel Extension assembly from inside the home.

3. Beginning indoors, install the 6 Phillips head wood screws through the SmartDoor into the wall, and into the 2” x 4” or 2” x 6” support beam installed earlier. Do not overtighten.

4. Moving outdoors, drill holes and install 4 Phillips head wood screws, one in each corner of the outside frame. These screws should pass through the frame, the wall, and fasten into the framing studs on either side of the framed tunnel.

5. Use window caulking to fill in any seams and gaps in your installation.

6. Install batteries. Your door is ready! You can begin training your pet.


Will I need additional extension tunnels for installing my large smartdoor into a drywall or brick wall?

It depends on how thick the drywall construction or brick installation is. If it is more than then 2" thick, then you will need additional wall entry frames along with the traditional framing that already comes with the door.

How can I make sure that my pet will fit the pet door?

First, follow our pet measurement guide to figure out if your pet needs a small to extra-large pet door. To double-check you have the right flap size, cut a hole into a piece of cardboard, and make the cut-out size the same as the flap dimensions. If your pet can walk through it easily, then you have the right size pet door. You can also use it as an outdoor cutout guide for cutting into your wall when installing the Petsafe Electronic Small Smart Door.

Where can I buy replacement flaps for the Petsafe pet products Electronic smart door?

You will need to buy replacement flaps for your electronic small dogs and cat door directly from the manufacturer. If you need a replacement flap for another door, check out our full selection of replacement pet supplies and accessories.
