Abstract: An apparatus is adapted for enabling a worker to install a top beam "C" clamp on a roof or ceiling beam, or to remove a previously installed clamp, without having to climb up to the level of the beam. The apparatus includes a structure for supporting the clamp and for positioning the clamp in an installation position on the beam or other suitable member. A socket assembly is associated with the clamp supporting structure and is adapted to drive either the clamp bolt or the nut received on the bolt when the clamp is properly supported on the clamp supporting structure. A driving assembly is connected to the socket assembly to enable the operator of the apparatus to rotate or drive the sockets to rotate either the clamp bolt or the nut received on the bolt. The socket assembly is adapted to be positioned through the driving assembly in either a bolt driving position or a nut driving position in which the bolt and nut, respectively, are properly engaged for driving.
