Abstract
A non-welded plate for supporting packing materials or limiting the upward movement of such packing materials in a packed column of a gas and liquid contacting apparatus is comprised of a plurality of first and second support beams. The first support beams have means for fastening to internal support members of the apparatus affixed thereon. The first and second support beams are essentially perpendicular to each other and are attached together by retaining means, such as a pin. Voids between the support beams may be covered with screen to provide further support or limitation.
