ABSTRACT:
A clamp particularly suited for pressure-filled fire hoses has a jaw configuration with three clamping edges with minimum spacing between jaw faces at the clamping edges arranged to effectively close off flow without slipping or twisting, structures for locating one or more hose sizes between the jaws to avoid bunching, and a cast support body and handle arrangement to facilitate operation in either of two positions.
