Abstract: A fabrication strip for use in construction of walls, joists, and rafters. The fabrication strip comprises an elongated strip of material having a base and a plurality of first and second tabs extending in the same direction from the base and being generally parallel to one another. The first and second tabs are spaced apart a distance corresponding generally to the width of the support member, e.g., beam, to which the fabrication strip is secured. The second tabs include a first portion extending parallel to the first tab and a second portion extending generally at right angles to the first portion. The second portions are spaced longitudinally on the base of the fabrication strip a predetermined distance from one another corresponding to the distance desired between adjacent studs extending parallel to one another. Placement of the studs against the same side of the second portions of the second tabs will properly space the studs from one another.

Abstract: An air distribution arrangement is adapted to be arranged in a cabinet for housing rack-mounted equipment that generates heat in use. The arrangement can be part of the cabinet when constructed or it can be an add-on feature. The arrangement includes plenum structure comprising side walls and a top wall that cooperates with the front door of the cabinet and the faces of the rack-mounted equipment to define a plenum. An air box in the cabinet draws ambient air from adjacent the floor into the plenum at a rate of at least 850 cfm. The ambient air is cooler than the air in the cabinet. The faces of the rack-mounted equipment have openings for receiving the ambient air to cool the interiors thereof. After cooling the rack-mounted equipment the air can be exhausted back to the ambient. The side walls and the top wall of the arrangement are adjustable to permit adjustment of the depth of the plenum. Pressure in the plenum can be relieved by slots in the plenum structure.
