Abstract: A double egress door frame has a channel-shaped header with upstanding sides connected by a central web. The central web has a first series of slots that are offset to one side of the central web and a second series of slots that are offset toward the opposite side of the central web. Door stops comprise a right elongated channel-shaped member and a left elongated channel-shaped member. The channel-shaped members are attached to the central web of the header by tabs extending from the sides of the channel-shaped members. The tabs engage the slots. Once the tabs have passed through the slots to the opposite side of the central web, the tabs are twisted thereby connecting the channel-shaped members to the central web. A spot weld is used to insure the door stops is permanently locked into position.

Abstract: The present disclosure provides a heat shield. The heat shield may comprise a first shield layer defining a cylindrical inner diameter surface of the heat shield, the cylindrical inner diameter surface having a radius and an axis, an air gap layer radially outward of the first shield layer, a second shield layer radially outward of the air gap layer, a first insulation layer radially outward of the second shield layer, a foil layer radially outward of the second shield layer, a second insulation layer radially outward of the foil layer, and a third shield layer radially outward of the second insulation layer.
