Systems for supporting loads which includes an elongated strut (or channel). A load-supporting component is fixed to the channel at a selected location therealong by a faster threaded into an associated channel nut. The channel nut is easily and quickly installed in the channel through a gap between flanges paralleling and spaced inwardly from the side walls of the channel and then rotated (and displaced along the channel, if necessary) to seat a lug on the nut in cooperating notches formed opposite each other in the flanges of the channel. This interfitting relationship provides a positive connection between the channel nut and the channel, keeping even heavy loads and loads subjected to vibration, hammering, or the like from slipping, even if the supporting channel is vertically oriented and the load is therefore the most susceptible to slippage. A double helical coil spring with biases the channel nut lug toward the bottoms of the notches to keep the channel nut in place until the load supporting component is assembled to the channel nut with the threaded fastener to lock the channel nut in place.
