US Patent 7661634 Keyed channel strut mounted connector device

A keyed channel strut mounted connector device includes channel engagement structure connected to attachment structure. The channel engagement structure includes a key for engaging the channel, and an octagonal neck connecting the key to a boss surmounting the attachment structure. The neck includes clearance facets permitting the key to pass into the longitudinal channel, and relief facets defining support shoulders on the key for supporting the key on the inwardly turned sidewalls of a channel strut. Two pairs of opposed support shoulders permit installation of the device for supporting a run of cables or pipes parallel with the longitudinal axis of the strut, or rotation of the device 90° for supporting the cables or pipes transverse to the strut. By rotating the device 180° in either direction, the head and tail ends of the attachment structure can be reversed without changing the parallel or transverse orientation of the attachment structure.
