Abstract
A tool for adjusting threaded valve boxes that grips the valve box from the inside. The present tool allows valve boxes to be rotated without having to excavate in the vicinity of the valve box, and thus allows valve boxes to be quickly and easily adjusted prior to or after paving. The tool is easily adaptable to a power-take-off unit, and automatically engages the valve box upon rotation of the shaft.
