Claim:
1. A fitting for a piece of channel framing including an elongate channel framing body having opposite longitudinal ends, a length extending between the opposite longitudinal ends, and a fitting side defining an external fitting groove extending lengthwise of the body, wherein the external fitting groove has opposite open groove ends at the opposite longitudinal ends of the channel framing body, the fitting comprising: a coupling component comprising an elongate body generally in the form of a block, the elongate body having opposite longitudinal ends, a length extending between the opposite longitudinal ends, a coupling longitudinal portion configured to be secured in the external fitting groove of the channel framing body, and an exposable longitudinal portion configured to extend outward from one of the open groove ends of the external fitting groove, wherein the coupling longitudinal portion of the elongate body has a generally double dovetail cross-sectional shape, whereby an upper portion of the coupling longitudinal portion has a length extending along the length of the elongate body and a generally dovetail cross-sectional shape for sliding insertion lengthwise into the external fitting groove, and a lower portion of the coupling longitudinal portion has a length extending along the length of the elongate body and a generally dovetail cross-sectional shape, which is inverted relative to the upper portion of the coupling longitudinal portion, for sliding insertion lengthwise in an external fitting groove of a different piece of channel framing to connect the pieces of channel framing to one another, wherein the length of the upper portion of the coupling longitudinal portion extends along the length of the lower portion of the coupling longitudinal portion, wherein the elongate body has opposite upper and lower faces and a first opening extending through the upper and lower faces, wherein the first opening is defined by the exposable longitudinal portion of the elongate body, wherein the elongate body has a second opening extending through the upper and lower faces, wherein the second opening is defined by the coupling longitudinal portion of the elongate body.
