Durability of the Endura Flap™ Design

Regular Vinyl Flaps

Anyone who has used a pet door for any length of time has seen that the cost of replacing the flaps can exceed the original cost of the door.

This sad fact is because most pet door flaps in use today consist of a sheet of vinyl fastened rigidly across the top of the frame with screws. As the pet goes through the flap it flexes. Worse, the pet must press upward against that flexed area to get full use of the space.

First the flap will 'potato chip' and begin leaking badly.  Eventually, the repeated flexing causes the vinyl to crack and tear in just the same way that repeated flexing of a coat hanger will cause it to break.

The Endura Flap™ Pivots!

If the Endura Flap™ material had to flex, it would fail in time also.

But it doesn't flex!

And that simple design difference allows the Endura flap to be flexible and extremely durable at the same time.

The Endura Flap™ is warranted against failure, except for chewing damage, for 15 years.

By the way, since this illustration was designed, the test machine went over 3 million trials. Same result.
