  • Patent number: 4098493
    Abstract: An improved woven wire partition that includes a frame fabricated of at least one channel member, that channel member opening outwardly relative to the center of the frame. A woven wire panel is connected with the frame, wire ends of the woven wire panel passing through holes in the channel member's center web and being folded over that center web to maintain the woven wire panel in connected relation therewith. At least one novel U-shaped clip is mounted in the trough of the channel member by frictionally interposing the clip's base between a folded wire end and the channel member's center web. The U-shaped clip's legs are sized to extend beyond the side edges of the channel member, and are configured to be received in an interference fit relation with the sides of an outwardly opening channel member of an adjacent woven wire partition when the two channel members are bolted together in side edge-to-side edge relation.
