Abstract: An air flow floor panel for a raised access floor system which includes an articulated frame surrounding a light weight grid component in egg-crate form. A laminated top plate having a plurality of holes therethrough is welded to the articulated frame and grid component and a pair of relatively slidable damper plates are secured to the bottom edge of the articulated frame by a plurality of S-shaped clips.

Abstract: A locking mechanism for locking a backless wall mounted cabinet or the like to a wall panel or partition having a pair of spaced slotted standards thereon adapted to receive a plurality of equidistantly spaced linearly aligned hook-shaped tabs on the rearward edges of the cabinet side walls. The locking mechanism includes a locking tab having a pair of spaced detents thereon, which locking tab is slidable from a first position adapted to enter the slots in the slotted standard with the hook-shaped tabs to a second position which locks the hook-shaped tabs into the slotted standard. A spring-urged locking pin is constructed and arranged to retain the locking tab in its second position.
