  • Pipe-stay clevis assembly
    Patent number: 5072903
    Abstract: The assembly is used for supporting pipes, etc from the ceilings of industrial buildings. Conventional pipe hangars are of screwed rod, (typically 3/8 inch) and the assembly includes a U-shaped clevis, which fits over the screwed rod. A bolt protruding into the space between the limbs of the U-shape engages the rod, and acts to clamp the clevis to the rod. The bolt lies off-center with respect to the rod. The bolt, when tightened, also clamps the clevis to a pipe-stay member of the assembly.
