The rigid, generally planar, rectangular first sheet, at least one rigid she et spacer mounted along, so as to protrude from, a first long edge of the first sheet, and a generall y "U"-shaped first channel formed along a second long edge of the first sheet, where the second long ed ge 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 do or frame member. The first channel includes a channel spacer protruding into the cavity.
