Abstract: Systems for supporting pipes and other loads which include elongated struts and channels that are fabricated from non-metallic materials and can be surface mounted. Clamps, connectors, and other fittings for attaching the supported load to the channel fit into cooperating notches in flanges spaced inwardly from the side walls of the channel. This interfitting relationship provides a positive connection between the fitting 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. Rounded transition sections at the ends of the notches facilitate the manufacture of the channels, minimize or even eliminate stress concentrations, and insure that loads supported by the system are satisfactorily distributed even if the fittings are tilted or canted relative to the channels.

Abstract: 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.
