Abstract: A connector for an office partition panel which has a rectangular panel frame at the edges thereof and a wire management channel formed at an upper portion of the panel. The connector rigidly connects the rectangular panel frames together at the side edges and includes upper and lower wedge blocks on the panel edges and draw blocks adapted to grip the wedge block and draw the wedge blocks of adjacent frames together. A draw tube connects the draw blocks. A wire management channel is formed at an upper portion of the wedge blocks and at least one upper wedge block has a U-shaped configuration with a wedge surface formed at a bight portion of the U, the legs of the wedge block extend up along the upper sides of the panel and in registry with the wire management channel. A change-of-height connector which has a removable wedge block adapter can be mounted to the side of the panel frame for changing height without use of a spacer or corner. A draw tube can form a spacer or corner between adjacent panels.

Abstract: An acoustic tile that provides soundproofing in a modular wall, such as is used in a modular panel office system, comprises a rigid rectangular metallic frame, a septum formed of a calcium carbonate-filled molded synthetic rubber polymer, a layer of low-density fiberglass and a layer of high-density fiberglass. The front of the frame is covered by fabric, and the back of the frame has fittings to attach the acoustic tile to a wall panel.
