Abstract: In a beam or pipe clamp, each of a pair of clamp jaw extenders is loosely coupled to a basic clamp jaw member and threaded onto the beam of the clamp so that the extenders oppose each other, between the basic jaws. Extender form may be chosen to provide greater capacity in terms of a deeper thrust between the clamp jaws or accommodation for irregularly shaped workpieces or both. Fit of the extender on the beam controls extender alignment relative to the beam and ensures that, while the basic jaw member may receive axial clamping forces, "tipping" force imposed on the extender is transferred directly to the beam.
