Our doors are available in different styles of sliding glass door inserts from door and wall mounts. Simple to install!

Custom Door Installs

Use your imagination for your custom door installation. Here are some examples of unique installation ideas.


The Solo Automatic Pet Door opens when your dog or cat approaches, then closes after it has passed through.
  • Distance settings are adjustable
  • Timing settings are adjustable
  • Only pets with a tag can activate the door
  • Pets with no tag remain inside
  • On/Off switch or Locking Pin to keep door closed
With a Solo Pet Door, you no longer have to replace your door every few years. If a part breaks or wears out, you simply order that part by itself and install it easily. As a result, many of our customers have owned their doors for more than 15 years.

Magnetic Pet Tags: The durable tinted Lexan© door slides open and closed via a collar tag. The pet door automatically locks securely; therefore, you can be absent and not have to worry about your pet or home security.

The magnetic pet tags last forever (unless your pet chews it off the collar). The pet tags do not require batteries so your pet will never get stuck and unable to use the door. The tags are waterproof and operate magnetically.

Our tags come in 5 sizes to accomodate all pets.
  • Tiny: e.g., Toy/Miniature
  • Small: e.g., Cat/Chihuahua
  • Medium: e.g., Beagle/Cocker Spaniel
  • Large: e.g., Labrador/Standard Poodle
  • Extra Large: e.g., Mastiff/Rottweiler/Great Dane

Pet Tag Sizes

We have designed and crafted our Solo Automatic Pet Doors to fit any dog or cat, with the pet’s safety and comfort always in mind.

A good way to determine the proper opening size is to measure your dog’s or cat’s height and width, then use a cardboard cutout to simulate an actual door. In addition, putting a treat on the other side of the “door” will provide incentive for your pet to pass through the opening.

Once you get your measurements, select a size slightly larger from one of our ten sizes. You want it slightly larger rather than smaller because your pet may become less agile as they age.
  • The overall height of the door is over twice as high as the pet opening (as shown)
  • The pet door frame is 4" thick
  • Dog door will protrude when installed on human door
  • Carefully measure for installations below a window
How to Measure Pet

Customers have owned our dog doors for 15 years or more and replaced only parts occasionally, due to the fact that the solid aluminum frame is permanently installed in either a wall or a human door (your choice).

We have provided a detailed diagram that shows every part, where it belongs, and its proper nomenclature, so that makes it a cinch to find and order the exact item.
  • Easily mount in a wall or human door
  • Can be adapted to fit any size exterior wall
  • Use 6-foot extension cord or hard-wire into wall
  • Can be installed by the homeowner, a handyman or contractor
  • On/Off switch to keep door closed
  • Use a smart plug to lock remotely

Optional intruder alarm* provides added security.
Once installed, if the door remains open for more than 12 seconds, an alarm will sound for approximately 60 seconds. In addition, it will shut off and AUTOMATICALLY RESET ITSELF. As a result, you don’t even have to be home to monitor it.

*Intruder alarm is available only at the time of purchase.  (Not available on Model 1008 or Model 1210)
