  • Does the pet door need to be installed on the door that swings open?

    The new glass with pet door can go on either the fixed side or the swinging side.

  • How long does it take to install?

    I would plan on 30 min to 1 hour depending on your comfort.

  • Are the panels/flaps flexible? Seems like it would trap a dog if it backed up.

    The Endura Flap is slightly more rigid than other economy style flaps, but it is a safe, soft, flexible flap. It remains flexible in temperatures as low as -40°F.

  • How does my small dog use the door if he can't reach it?

    We suggest you email us at sales@utahpetaccess.com to go over your specific height requirements and we can send you the appropriately sized door for your needs.

  • Do I need a professional to install my Endura Flap Door Glass?

    This product can be installed by anyone with ambition to take on the project. If you feel less comfortable taking it on, we suggest a handyman. We serve the greater Salt Lake City area and have contractors in several states. Give us a call at (801) 652-9446 for a consultation and appointment.

  • What are the benefits of a pet door in glass vs the wall or a door?

    We love the fact that you can use this product and then take it with you when you move. No hassle of buying a new door or hiring several contractors to fix the hole you cut in your home.

  • Is a single flap enough for winter weather?

    A single Endura Flap is extremely energy-efficient and capable of withstanding winds up to 50 mph. It is the only door which allows you to increase the magnetic strength for increased wind resistance. It is recommended for timid pets. The double flap increases the energy-efficiency further.

  • Does the door sound very loud when the dog goes in or out?

    When the flap gets to its resting place there is a snapping sound when the magnets employ. This sound lets you know the door is doing its job sealing out the elements and keeping your heated or cooled air inside.

  • Other brands of pet doors with plastic flaps always warp and thus let in air. How do these flaps hold up over time?

    The Endura Flap is made with a special polymer called polyolefin. It remains safe, soft and flexible in temperatures as low as -40°F. It does not yellow nor harden in the sun. The patented magnetic design ensures the door seals well for years. In fact, the pet door and flap are backed by a Lifetime warranty. To contact Endura Flap for door warranty email a photo to our customer service team, and we can look and let you know.
