Connector

A connector for a channel having a web and side flanges with inwardly turned lips defining a slot therebetween, said connector comprising a channel-shaped connecting member having a pair of opposed side walls with longitudinally extending edges and a connecting wall having a circular opening therein, a relatively flat thin round screw member threaded in said opening and having opposing end faces of substantially the same diameter, said screw member being threaded substantially from one end face to the other for being threaded in said opening, said connecting member being adapted to be axially inserted inside the channel with the open side of the member toward the channel slot to a position in which the side walls of the member are adjacent and generally parallel to the side flanges of the channel with the longitudinally extending edges of the side walls spaced from but adjacent to said lips of the channel, and in which the connecting wall of the member is adjacent and generally parallel to the web of the channel with the screw member in position for engagement of one end face thereof with the web of the channel on rotation of the screw member thereby to force the connecting wall of the connecting member away from the web of the channel and said edges of the side walls of the connector into locking engagement with the lips of the channel rigidly to secure the member to the channel, the thickness of said screw member being such that when said connector is in locking engagement with said channel, the other end face of the screw member does not project substantially beyond the surface of said connecting wall opposite the web of the channel, said screw member having a slot therein.
