ABSTRACT:
A tool for removing a cap from a pipe. A torque screw is threadedly mounted to a frame having a pair of downwardly extending legs to which is attached a ring slippable over and against a sewer pipe. A pair of fingers are pivotally and rotatably mounted to an end of the screw and are positionable between the end cap and the end of the sewer pipe. Rotation of the screw forces the fingers and cap apart and away from the ring and pipe.
