Built like a rock, but as safe as a traffic cone!
We know that headliner is a bit confusing but follow us here as we explain. This dual direction pet door is made from an aluminum welded frame that houses a clear Plexiglas panel. This makes your door as hard as a rock and able to withstand any dog or weather abuse. The high tension springs located in the hinges automatically close the panel behind your pets to eliminate the release of home heating and air and the entrance of outdoor elements. That would be the rock part. The easy to use yet sturdy door is large enough for dogs over 120 pounds yet is simple and light enough to be used by a 7-week old black lab puppy. The Plexiglas panel is chew proof so that your pup does not hurt himself on the door. Thats the safety in mind represented by the traffic cone. For more metaphors, look at our other dog doors after you purchase this one!

Operating:

• When your dog goes "out" the door - the Plexiglas panel and the Outer welded aluminum frame move.
• When your dog comes "in" the door - the welded aluminum Outer frame stays stationary and only the clear Plexiglas panel moves.

Unlike other drafty doors, this system is guaranteed to seal weather-tight and save you from wasting energy or money. This door system has been commercial tested and can withstand the heaviest use from the biggest pets.
