A Pet Door Flap that Keeps Your Home Comfortable

  • The Endura Flap uses magnets to provide a seal against air escaping. It has magnets on each side of the opening and is supplied with extra ones to make a stronger seal if weather conditions require.
  • The Endura Flap has a double layer construction which is thicker than most glazing units, and this excellent insulation is reinforced by internal sealing bars which restrict the movement of both warm and cold air.
  • The flap can be relied on to exclude even the iciest draughts, and in rigorous tests it remained firmly closed against winds exceeding 50 mph.

The Safe Way to Give Your Pet Independence

  • Unlike most pet doors, the Endura Flap is not made from vinyl (PVC), but from an advanced polymer. This material is extremely strong, but also soft and supple that it won’t cause injury or discomfort to your pet.
  • All sizes of the Endura Flap feature a taller, narrower aspect ratio (height: width) than normal, which allow them to be mounted close enough to the floor for easy access by older or less agile animals.

Give Free Access to Your Pets and Nothing Else

  • You want to allow your pets their freedom, but not if it puts the security of your home at risk.
  • Unfortunately, poor design means that many pet doors fail this basic test. As they become taller to accommodate larger pets, they also become wider so that intruders may get through.
  • Endura Flaps are designed with an aspect ratio which will allow your pet entry but exclude any unwanted human visitors.
  • You will also get a secure locking cover for use overnight or when you’re away.

Look Forward to Years of Use

  • Unlike brittle vinyl, the Endura Flap’s special polymer won’t break in the cold; and an ultra-violet retardant treatment also prevents it cracking, wrinkling or yellowing in the sun.
  • In tests, the Endura Flap opened and closed more than 3 million times without any damage.
  • By contrast with mass-market options, the Endura Flap is a precision engineered product, manufactured in the USA, which you can confidently expect to be using for many years.

Enjoy Peace of Mind with Manufacturer’s 15-Year Warranty

As a valued Endura Flap™ owner, you will be protected by a comprehensive 15-year manufacturer’s warranty against any defective materials or workmanship.

How Energy Efficient Endura Flap Pet Doors?

Compared to your typical dog door , Endura Flaps are much more energy efficient. The secret is in the magnets, which work to create a strong seal from the dog door to your actual door. These magnets are designed to secure the door to each side of the Endura Flap opening, keeping cool or warm air from escaping your home while also keeping the likes of rain, snow, and wind from entering it. These features combined with the pet door’s high-quality build enable Endura Flap to function as a much better insulator than the conventional pet door. Throw in the fact that Endura Flaps are available in double flap models, and they can set a new standard in dog door energy efficiency.

How Easy and How Much Time Does an Installation Take?

Endura Flap is incredibly easy to install, one of the reasons why we often refer to it as a “DIY pet door.” We’ll just need you to send us the width, height, and thickness of the current panel in your sliding door, we’ll send you a replacement panel, and you should be able to take things from there. To install your Endura Flap, you’ll simply need to remove your sliding door and the glass from the frame and then slip in the pet door conversion system in its place. It’s really that easy – all you’ll need are a few simple hand tools. If you’re still not comfortable installing the Endura Flap yourself, Contact Pet Door Products for sliding glass pet door installation in Utah.If you need a pet door installed outside of Utah, choose from the directory of Pet Door Pros to find a local dog door installation in your area.

What Is the Biggest Dog Your Pet Doors Can Accommodate?

Both our single and double flap options can accommodate dogs weighing up to 220 pounds, which should be adequate for the vast majority of pets.

Are There Color Options for the Pet Door Flap?

Yes, the product is available in three different colors to match your door. Endura Flap is offered in white, light tan and dark tan colors.

Should I Choose a Double or a Single Flap?

The double flap model is ideal for pet owners who want to give their home an extra layer of protection against Mother Nature. For example, if you live in a northern climate where the weather varies by season, the double flap model can come in especially handy on those cold winters and hot summer days. If you live in an area that sees more consistent year-round temperatures, the extra layer of weather resistance may not be as necessary.

Will My Dog Have a Hard Time Learning to Use the Endurance Flap Pet Door?

While there may be some minor adjustments your dog will have in getting used to the pet door, it’s unlikely to be a significant adjustment. Most dogs figure out how it works within minutes!

Can the Endure Pet Flap Be Used for Cats?

Yes, Endura Flap can be used for cats too! Single flap Endura Flaps are offered in dimensional sizes as small as 6 x 11 inches, an ideal size for most house cats to comfortably pass through.
