Abstract: A duct manifold including a first duct, a second duct, and a coupling. The first duct includes a first duct body, a duct extension, and a first duct flange. The duct extension extends from the first duct body. The first duct flange is coupled to the duct extension, and the duct extension extends beyond the first duct flange such that a flange support is defined on an end of the duct extension. The second duct including a second duct body and a second duct flange coupled to the second duct body. The coupling is configured to couple the first duct to the second duct, wherein the second duct flange rests on the flange support when the coupling couples the first duct to the second duct.

Abstract: A portable door lock (10) which is releasably coupled to door frame (12) and a door member (14) for positionally constraining the door member (14) to the door frame (12) when the portable door lock (10) is in an operational mode. The portable door lock (10) includes a door engagement mechanism (16) which is insertable between the door member (14) and the door frame (12) at the interface thereof. The door engagement mechanism (16) matingly engages the door member (14) on front and rear surfaces (20 and 22) and contacts the door frame (12) on a rear surface (24). A locking bar mechanism (62) is longitudinally displaceable on the door engagement mechanism (16) and extends across the interface (18) of the door member (14) and the door frame (12) for contacting the frontal surfaces (20 and 64) of the door frame (12) and the door member (14).
