When the flap gets to its resting place there is a snapping sound when the magnets employ. The double flap increases the energy-efficiency further.ĭoes the door sound very loud when the dog goes in or out? It is the only door which allows you to increase the magnetic strength for increased wind resistance. Is a single flap enough for winter weather?Ī single Endura Flap is extremely energy-efficient and capable of withstanding winds up to 50 mph. It remains flexible in temperatures as low as -40☏. The Endura Flap is slightly more rigid than other economy style flaps, but it is a safe, soft, flexible flap. There has been lots of discussion as to why the Endura Flap is such a high-performing pet door, but for engineers or those looking for some more technical information here is a 74-page dog door energy efficiency study showing what makes it so special.Īre the panels/flaps flexible? Seems like it would trap a dog if it backed up. Option to add or decrease magnet strength, perfect for training pets or increasing already significant wind resistance.Four sizes available from small for cats to extra large for large dogs like Great Danes designed to accommodate most breeds.
