Great for pets: The dog door can confine your pet to a certain area, avoiding your pet from disturbing you while you are working or cleaning the room. Suitable for dogs, old cats, rabbits and other pets. The product is not indestructible and is not suitable for pets who like to chew. Easy to assemble: Follow the detailed instructions to install, insert the connected tube into the inner edge of the nylon fabric to build the door frame, and then use the bracket to fix the door to the wall/door frame. The dog door can be easily disassembled and stored to save space. The product has been improved many times: 1. The plastic tube is improved to a hollow iron tube, which is more durable. 2. The package contains two connection methods. You can choose to punch holes or stick to the wall. 3. The nylon surface is thicker and can resist scratching by pet claws. Install anywhere: The pet door can be used to separate corridors, kitchens, bedrooms, stairs; it can prevent dogs from damaging furniture, sofas or misbehaving. Although the pet safety door is installed, you can still clearly monitor your pet's activities through the nylon net. Size: Length: 100 cm, height: 80 cm, suitable for most front door sizes. The dog door is lightweight and sturdy and will not hurt your pet. It is recommended to install three brackets, two self-adhesive brackets on the closed side and one on the top of the open side, so that it is more convenient to open or close the door.
