Abstract
A connector for a channel having a web and side flanges with inwardly turned, hook-shaped lips defining a slot therebetween. The connector comprises a channel-shaped connecting member having a pair of side walls with longitudinally extending edges and a connecting wall having a circular opening therein. The connector further comprises a relatively flat thin round screw member threaded in the opening and having opposing end faces of substantially the same diameter, the screw member being threaded substantially from one end face to the other. The member is 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 parallel to the side flanges of the channel with the longitudinally extending edges of the side walls spaced from but adjacent to the lips of the channel, and in which the connecting wall 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 web of the connector away from the web of the channel and the edges of the side walls of the connector locking engagement with the lips of the channel rigidly to secure the member to the channel. The thickness of the screw member is such that when the connector is in locking engagement with the channel, the other end face of the screw member does not project substantially beyond the surface of the connecting wall opposite the web of the channel.
