Here are answers to some of the most frequently asked questions about the extraordinary Endura Flap pet door featured in all Pet Door Products dog doors:

Can a Large Dog & Cat Use the Same Double Flap Door?

Pet Door Products dog doors for large dogs feature relatively strong magnetic seals that might hold too snugly for some cats to pass through easily. But, there’s an easy adjustment that can be made. If you have both a cat and a dog sharing a pet door, you can reduce the resistance from the magnets along the pet door threshold as much as needed to lighten the strength of the closure. You can make that adjustment for any size of Pet Door Products dog door.

Can I Install This Door Into My Glass Door?

This pet door is not designed for installation in a regular single- or double-pane glass door. Pet Door Products advanced design is a pet door insert for sliding glass door installation. But, if you have a sliding glass door, our dog door for sliding glass door model could be ideal for your pet and your home. It features the same flap used for inserting into that door type.

Does the Door Sound Very Loud When the Dog Goes In or Out?

You may hear a slight clicking sound when the door closes as the magnets engage. That sound is your indicator that your new pet door is functioning well and sealing out the hot or cold exterior air and other weather elements to keep the interior of your home comfortable.

I Do Not Have to Contend With Wind or Rain, if I Buy the Single Flap Version of the Wall Dog Door Is It Possible to Add the Second Flap in the Future?

Yes, you can add the additional flap later if you wish. However, that approach to upgrading a single flap to a dual model involves a relatively complex set of tasks and can be expensive. You would need to buy a new frame for either the interior or exterior side of the opening. That’s because the pet door frames made for single flaps are configured slightly differently than those for the Endura Flap pet door double flap models.

Is a Single Flap Enough for Winter Weather?

Our single flap pet doors are exceptionally energy-efficient. These advanced pet doors seal out the weather elements ideally. They’re built to withstand winds as high as 50 mph! Pet Door Products Endura Flap dog door is the only one on the market with adjustable magnetic closures that can be set up for greater or less wind resistance. The single flap is recommended for pets that may be intimidated by the double flap. For pets who pass unconcerned through a double flap door, you can add the double flap for an extra measure of thermal effectiveness.

Is This Flap Flexible?

The Endura Flap is a little firmer than some other dog door flaps, but it is a soft, flexible, safe, and comfortable pet door flap.

What Makes This Door So Great?

What makes the famous Endura Flap pet door so much higher quality and better performing than any other dog door built today? It offers homeowners an exceptionally energy efficient pet door, and its strength, comfort of use for pets, and long-term durability are unsurpassed.

Why Is There a Difference in Pet Door Flap Size for the Single Versus the Double Flap Models?

Every Endura Flap is built with double-wall construction, which means they’re almost an inch thick (7⁄8″). When your pet pushes against the first flap to open the pet door, that flap pushes against the second flap and opens it. A narrow space remains along the top of the pet door opening between the two flaps. The second flap is designed to fit with the slightly different parameters of one side of the door that accommodate the different setup of the second flap.
