Clevis hanger

A clevis hanger for supporting conduit comprising:

• a U-shaped lower hanger member having a pair of generally parallel arms, each arm having an upper end;
• an upper hanger member having a pair of spaced-apart arms depending generally downward therefrom, each arm of the upper hanger member having an upper portion, a lower portion and a lower end, the lower portion of the two arms of the upper hanger member being horizontally spaced apart such that said lower portions are located adjacent the arms of the lower hanger member;
• each of the arms of the lower hanger member and each of the lower portions of the arms of the upper hanger member having an opening therein, the openings being in generally horizontal alignment with one another when the upper and lower hanger members are connected;
• an elongate fastener adapted to be inserted through said aligned openings to connect the upper and lower hanger members;
• and
• means for limiting rotation of the lower hanger member relative to the upper hanger member;
• the clevis hanger being configured such that when the fastener is inserted into said aligned openings, the means for limiting rotation permits the lower hanger member to swing freely on the fastener through an arc of predetermined length, but limits swinging of the lower hanger member beyond said arcs
• said means for limiting rotation comprising stop means on the arms of one of the upper and lower hanger members, said stop means being positioned such that the arms of the other of the upper and lower hanger members are engageable with the stop means to limit swinging of the lower hanger member beyond said arc.
