Abstract: The rigid, generally planar, rectangular first sheet, at least one rigid sheet spacer mounted along, so as to protrude from, a first long edge of the first sheet, and a generally “U”-shaped first channel formed along a second long edge of the first sheet, where the second long edge is opposite the first long edge. The first channel opens towards the sheet spacer so as to define a cavity therebetween and along the length of the first sheet. The first channel is sized so as to fit over, as an end cap on, an exposed long edge of a door frame member such as a door jamb or a center frame member of for example a double width door when so fitted, a distal side wall of the first channel, distal from the first sheet, is mated to a first side of the exposed long edge of the door frame member. The first channel includes a channel spacer protruding into the cavity.
