Abstract
Abstract A cast iron pipe hanger clamp having a solid body with upper and lower jaws projecting from one side, and a boss projecting from the center of the opposite side and braced by upper and lower pairs of spaced flanges. The boss has a threaded bore with jam threads to receive a threaded pipe hanger rod between the spaced flanges, the load of the supported weight being distributed and loading the upper flanges in tension. A setscrew in one jaw locks the clamp in position and loads all four flanges in compression, reducing or eliminating tension load in the upper flanges.
