PlexiDor Extra Large Dog Doors are chew proof – GUARANTEED. We have applied many of the features from our commercial kennel doors used by military and police worldwide to bring you a virtually indestructible dog door. PlexiDor’s patented panels are saloon style and do not require costly replacement flaps. The hardened aluminum frames come in a silver, white or bronze finish to coordinate beautifully with your appliances, interior walls or hardwood floors. Each Medium, Large and Extra Large PlexiDor includes a cylinder lock, key and steel security plate. The door can be locked every night and the steel security plate can be attached while you’re away for an extended period of time. PlexiDor Performance Pet Doors are extremely energy efficient. Each time you open the door to let your dog out, your heating and cooling escapes. Installing a PlexiDor Dog Door can save you money. On average, homeowners have reported an annual savings of 10% off their energy bill. The PlexiDor Extra Large Units are designed for dogs weighing up to 220 pounds.
