FAQ
Are replacement flaps available? Currently, we do not carry any replacement flaps for this door. You would need to go to the manufacturer’s website to order them. |
Are these electronic pet flaps? Unlike the rest of High Tech Pet Doors’ products, the Armor Flex pet door is not an electronic smart door. It is a traditional pet flap that is opened by the pet pushing it open. |
Are there color options other than white? No, but you can paint the frames with speciality paint from your local hardware store. |
Can a large dog & cat use the same door flaps? We recommend getting dogs and cats different doors. While the flap is lightweight, it is sealed shut with non-removable magnetic, which may make it hard for a cat to push open. If you need an in-wall pet door with removable magnets, we recommend checking out the Endura Flap Pet Door for Walls. |
Do I need to buy separate wall tunnels for this door? No, this comes with a tunnel that can fit into walls up to 7” thick. If your wall is thicker than 7” or the tunnel that came with your door is damaged, you may need to purchase a new tunnel. The wall tunnels can also be used to convert an Armor Flex Pet Door for Doors into an in-wall pet flap. |
How do I know what size is best for my dog? When installing the Armor Flex wall door you want it to clear the top of your dog's back by 1-2 inches, minimum. You also want the step over to be comfortable. Lastly you want the width to allow your pet to go through without touching the sides. Here's a measurement guide with tips on how to determine the correct size. |
