Abstract
A wrench tool suitable for use by firefighting personnel. The tool has an elongated handle, and a spanner part at a first end of the handle. The spanner part has a projecting claw for operatively engaging a pin on the circumference of a pipe or a hose coupling ring to be rotated by the tool. A wrench part, at a second end of the tool handle opposite the first end, has jaws arranged for adjustable relative movement to grip an object to be turned by the tool. The range of movement of the jaws includes a position at which the jaws are set to receive and safely grip an outside levering tool for producing increased leverage when operating the spanner part of the tool.
