The fastener comprises an elongate body or nut having inside and outside faces, opposite sides and opposite ends, a width less than that of the slot and a length greater than the width of the slot. The fastener also includes a clamp member secured to the body having portions generally adjacent opposite sides of the body engageable with the outside face of the framing when the body is aligned with, entered into and passed through the slot in the framing. These portions remain substantially stationary with respect to the body when the latter is turned to its crosswise position. The clamping member also has resilient clamping portions generally adjacent opposite ends of the body engageable with the outside face of the framing when the body is turned to its crosswise position.

Abstract: A hanger for attachment to a vertically disposed threaded support rod or the like for supporting a pipe or the like in generally horizontal position. The hanger comprises a support member of relatively resilient material which engages the undersurface of the pipe and which has a pair of legs extending upwardly at opposite sides of the pipe. The upper ends of the legs are bent laterally inwardly toward one another to form upper and lower generally horizontal overlapping flanges which overlie the pipe, each flange having an opening therein for receiving the support rod therethrough. A nut is held captive but rotatable with respect to the support member adjacent these flanges, the nut having a threaded hole generally in register with the opening in one of the flanges.

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.

Abstract: A fastener for securing parts to metal framing such as channel framing having side flanges with inwardly turned, hook-shaped lips defining a slot therebetween. The fastener comprises an elongate body or nut having inside and outside faces, opposite sides and opposite ends, a width less than that of the slot and a length greater than the width of the slot. The fastener also includes a clamp member carried on the outside face of the nut for engaging the curved outside faces of the channel lips, a retainer on the inside face of the nut and engageable therewith, and guide members extending from the clamp member to a position beyond the inside face of the nut and the retainer. At least one of the guide members has a portion bent to provide a spring finger engageable with the retainer for providing spring action tending to draw the clamp member in the direction back toward the outside face of the nut thereby to clamp the clamp member and nut against respective outside and inside faces of the channel lips.

Abstract: A connector for a channel, the latter having a web and side flanges with inwardly turned, hook-shaped lips defining a slot therebetween. The connector comprises an elongate connecting member generally U-shaped in cross-section having a pair of side walls. The member is axially inserted inside the channel with the open side of the member toward the channel slot and the side walls of the member adjacent and parallel to the side flanges of the channel. A cam is mounted in a side wall of the member for movement from a retracted to a locking position in which the cam engages a lip of the channel when the member is inside the channel to force the member toward the web of the channel for engagement therewith thereby rigidly securing the channel to the member.
