ABSTRACT:
A clevis hanger for supporting conduit comprising a lower hanger member formed from a strap of metal bent into a generally U shape and having an arcuate bottom and a pair of generally parallel arms extending upwardly from the bottom. The arcuate bottom has a middle region generally midway between the arms for supporting the conduit. An upper hanger member has a pair of arms depending generally downward therefrom, and each arm of the upper hanger member has a lower portion. Each of the arms of the lower hanger member and each of the lower portions of the arms of the upper hanger member has an opening therein. The openings are in generally horizontal alignment with one another when the upper and lower hanger members are connected. An elongate fastener extends through the openings to connect the upper and lower hanger members. The middle region of the arcuate bottom of the lower hanger member has, as viewed in transverse cross section, a central portion and two side margins extending laterally outwardly from the central portion such that the central portion forms a ridge on an inner surface of the arcuate bottom.
