Aluminium

Pet-Tek  Aluminium doors "Dog walk" are designed to be aesthetically pleasing whilst maintaining complete durability. The dog door frames are manufactured from tough anodized or powder coated aluminium. No fixing screws are visible giving a clean and smooth picture frame appearance once fitted. All flaps are made from Thermoplastic Polyurethane (TPU) Plastic Resin. This is an extremely tough material which is tear resistant and remains flexible at extreme hot and cold temperatures unlike and will not go brittle. Used by the Germany Military special, forces to make light weight collapsible kayaks. All dog doors have an aluminium composite security slide to help prevent intruders.
Doors are available in both door mounted and wall mounted options with ether single or dual flaps for the colder climates or, to help reduce air conditioning costs in the warmer climates.
