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. 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
