Installs into your door or wall

Comfort King’s pet doors are a perfect fit for any exterior door, including wood, fiberglass, and steel. The doors are available in small, medium, large, and extra large to accommodate whatever size of dog, cat or whichever pet you own. Their aluminium frames can be coloured bronze, silver, and white and will never rust, warp, or crack.

If an exterior door is not available, The pet doors can also be installed into exterior walls of stud, brick, block or cement up to 12 inches thick. The door includes an aluminium tunnel ensuring everything is sealed; it has no sharp edges and will never rust. An outward slope carries water out of the tunnel and away from the door, plus it is easy to clean.

Built-in Security Features

A lock & key included with every pet door

Every pet door comes a lock and key to secure the doors shut. The metal lock is on the inside half of the pet door to preventing tampering. Simply turning the key will lock the doors in place. Small-sized pet doors feature a 4-way lock: unlocked, locked, unlocked-entry, unlocked-exit.

A steel security plate included with medium doors or bigger

For pet doors of medium size or bigger, a steel security plate is included. The plate easily screws into the pet door frame on the indoor side and blocks passage. Frequent users should consider the sliding track for easier operation.

Electronic Series Pet Doors

Comfort King’s electronic pet door is available for people with large animals looking for an automatic yet secure product. The composite door is secure while shut to prevent the doors opening, but opens like a garage door with the help of a small motor. It can be plugged in to a standard outlet or hardwired.

A state-of-the-art RFID collar key remotely opens and closes the door within a short distance; the length of time the door is open can be controlled manually. The collar key is waterproof and weighs under 0.5 ounces; an easy attachment to your pet’s collar.
