Introducing the Endura Flap -
The greatest advance in pet door design ever!
The heart of any pet door is the flap, and pet door flaps have
always been a big disappointment to the pet door owner. They leak,
they don't insulate, they pinch the pet, they blow open, they don't
fit the pet and they wear out quickly so the user needs to buy an
expensive replacement flap and start over again.
Some have been better than others in one respect
or another. But none has ever succeeded in achieving superior
performance in every respect. This is particularly true of the
brands that are most heavily marketed today.
Beginning in 2001, Patio Pacific, Inc, undertook
an intensive engineering design effort to build the perfect pet door
flap and, based upon that design, to produce a full range of
superior pet door products. By Fall of 2004, that work had
culminated in the "Endura" Flap Assembly.
The rest of these pages are devoted to a
presentation of the patented Endura Flap Assembly design through a
discussion of the major design criteria.
If you've ever owned a pet door, you're going to
love what you see here.

these engineering drawings to emphasize various components of the
flap design. |
