Abstract: A bed frame end board that can be easily disassembled and reassembled to replace damaged components and reduce the cost and labor associated with refurbishment of dormitory beds including a vertically oriented rail configured to interlock with a bed frame side member, an outboard panel, and an inboard panel; and vertically spaced apart cross members having opposite ends fixed to the posts, wherein the outboard panels are releasably fixed to the rail by a fastening system having a slotted fastening clip on the rail and a stud on the outboard panel engaging a slot in the clip, and wherein the cross members are releasably attached to the posts with a threaded fastener and stabilized against rotational movement with respect to the post by dowels received in aligned bores extending into abutting surfaces of the panels and posts.

Abstract: A vented laboratory cabinet from which vapors and fumes may be effectively exhausted from all parts of the cabinet includes an interior storage space defined by a plurality of panels that are accessible through a closeable door, at least one shelf carried within the cabinet interior, and a vent pipe extending downwardly from an exhaust opening toward a lower part of the cabinet. Improved venting is achieved with a vent pipe having at least two vertically spaced apart vent openings for passage of gases from the cabinet into the vent pipe, wherein at least one of the vent openings is located above the shelf and at least one other vent opening is located below the shelf. The improved vented laboratory cabinet provides effective evacuation of fumes from both sides of the shelf, whereby accumulation of chemical vapors is reduced or eliminated.

Abstract: A wall rail system includes a cabinet rail having a base portion and a hook portion which projects away and downwardly from the base portion, the front of the cabinet rail being free of sharp edges, and an elongate wall rail including a base portion and a hook portion which projects away and downwardly from the base portion, with the front of the elongate wall rail also being free of sharp edges, whereby the front of the cabinet rail can smoothly slide over the front of the wall rail and guide the hook portion of the cabinet rail into a channel defined by the base portion and hook portion of the elongate wall rail during installation of a cabinet unit. The absence of sharp edges on the fronts of the wall rail and cabinet provide easier installation and reduce the potential for damage to walls and/or cabinet units by inadvertent contact with the rails during installation.
