A wire roller includes a wire receiving spool rotatably supported on a frame adapted for support on a vehicle. The power means for rotating the spool includes an electric motor supported on the frame and coacting drive means on the motor and spool for rotating the spool in response to operation of the electric motor. The frame may be supported on a vehicle by a clamp assembly including a pair of coacting clamp jaws which are pivotally connected together by an adjustable connection for accommodating bumpers of various dimensions. A torque applicator is operatively associated with one clamp jaw for pivotally moving said clamp jaws into clamping engagement on a vehicle bumper.
