Pet friendly. Let your pet in and keep unwanted critters out with our built-in pet door. These half screen doors combine function and style, letting the light in while letting your dog in and out! Don't worry about unwanted critters--the built-in pet door features an inside panel that slides down to close the flap. The screen is reversible for top or bottom ventilation. Our half screen and solid core doors seal out the weather with heavy-duty weatherstrip systems. Built on a 1 inch thick solid core and finished with our age and weather resistant DuraTech®, these doors provide the ultimate value when it comes to weather protection. #WelcomeHome #MyLarsonDoor #ItsADogsLIfe
