Abstract
A tool for operating a subterranean utility valve having limited accessibility includes a hollow housing with a plurality of elongated members mounted for sliding movement within the housing. Each elongated member is movable in a direction away from the first open end of the housing for placement about a valve nut of such utility valve. A handle is connected to the housing for biasing elongated members for engagement with such valve nut and for generating a torque enabling rotation of such valve nut in order to control flow through such utility valve. A rigid member is connected to plurality of elongated members for retaining and remotely moving them within the hollow housing.
