摘要： Two slot forming components overlay through a pre-formed wall opening to form an adjustable wall passthrough slot. At least one slot surface has an intumescent layer of material positioned out of the way of documents passing through the slot. Heat from a fire will expand the intumescent material to fill the slot and prevent the spread of fire. Two inclined top and bottom slot surfaces are positioned in parallel and spaced apart by the desired thickness of the slot. A smoke shield flap of flexible fabric material hangs down within the slot to prevent the passage of smoke through the slot while allowing documents to pivot or push the smoke shield flap aside.

摘要： Disclosed is a device for supporting acoustical ceilings and other suspended objects. The device includes a clamp that is removably inserted into an outer sleeve. The exterior wall of the clamp includes threaded elements that can mate with threaded elements disposed on the interior wall of the outer sleeve so that the clamp can twist in and out of the outer sleeve in a screw-like manner. The clamp includes a cavity for securing a ceiling wire therein, wherein the ceiling wire can be attached to an overhead ceiling structure. The outer sleeve is removably secured to a ceiling grid. In use, the clamp can be repositioned within the outer sleeve to adjust the height of the ceiling grid. In this way, the present invention can be used in construction and commercial applications in a convenient manner, thereby simplifying the process of providing support for acoustic ceilings.
