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.
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. |
