Built for Pet Comfort
Patented comfort feature called "stepover" is available on our entire line of Endura pet doors. The exclusive user adjustable step-over will match pet door height to pet height after purchase. Built-in Anti Whoops in case your measurements are slightly off.
Step-over is the height of the flap above the base of the pet door.We suggest that 'flap height' + 'step-over' should about equal pet shoulder height. Unlike any other panel pet door on the market, the Thermo Panel IIIe can be adjusted by the user to the step-over dimensions shown, in 2" increments.
Step-Over is very important to the comfort of your pet. A higher step-over gets the flap up higher for a taller dog which avoids him having to stoop to get through.
On the other hand, a lower step-over is less to 'step over'.
In the past, a consumer that wanted a different step-over for any reason had to buy another patio pet door. If you misjudged and got a door with too tall a step-over you were in trouble. Likewise, if you replaced a short pet with a tall pet or vice-versa, you had a problem.
The adjustable step-over concept greatly increases your flexibility with the pet door. By simply removing the bottom flap assembly and cross pieces with a Phillips head screwdriver, you can rearrange the order of the cross pieces to get the step-over higher or lower.
Note: Endura Flaps™ are not recommended for use by kittens or very small dogs. Adult cats have been successful using the Small #06 and Medium #08 . We would not recommend using the Large #10 or Extra Large #12 for cats.
