ABSTRACT:
A beam clamp retaining strap has a beveled locking slot for securing to a threaded hanger rod or set screw of a pipe support assembly mounted to an I-beam. The assembly further comprises a C-type clamp, and the strap may be positioned in any of four possible locations with respect to the clamp, rod, and set screw. The slot edges securely engage between the major and minor thread diameters of the rod or screw. The beveled locking slot provides additional assurance that the clamp grip does not loosen such that the pipe assembly is dislodged, and, thus, the need for an additional nut for the retaining strap is thereby eliminated.
