US Patent 7188826 Internal clip for a rail

A resilient clip adapted for internal installation within a rail having a longitudinally extending internal gap. The clip includes a lower leg that engages the base of the rail, and an intermediate leg, which engages a side wall of the rail. An indented upper leg of the clip is capable of clamping an elongate line, such as an electrical or communication line, in an elevated position in the upper section of the rail. Plural clips may be installed in the rail to support such a line at multiple spaced points along its length. A strengthening cable may be installed in the lower section of the rail, in overlying relationship to the lower legs of the clips.
