ABSTRACT:
A metal frame includes top, bottom and side members, each member having an angular cross section. A sheet metal door of unitary construction is formed with a tubular portion at its upper end and a pair of spaced panels depending therefrom. A pair of plastic bushings are loosely received in the opposite ends of the tubular portion, the bushings having flanges that determine the small amount of clearance between the door and the sides of the frame. A rod extends through the bushings and through the flanges of the angled side members to determine the small amount of clearance between the frame and the top and bottom of the door. In this way, the door is free to swing inwardly and outwardly, thereby permitting a dog to readily enter or leave the doghouse.
