The only two-way dog door on the market with “special” heavy-duty spring loaded hinges that provide a positive weather seal! When your dog goes “out” the door, the inner clear plexiglass panel and the outer welded aluminum frame move. When your dog goes in the door, the welded aluminum outer frame stays stationary and only the inner clear plexiglass panel moves. The 12-1/2″ x 17-1/2″ opening of the Heavy Duty Dog Door® is large enough for a dog up to 120 pounds and the door swings easily enough to be operated by even 7-week black lab puppies. Frame size 14″ x 20″ – entrance size 11″ x 15″ Installation Tip: Install 1/8″ felt or rubber weather stripping on surface of building or door to help prevent air leakage and lessen flap noise.
