The extendable arm of the present invention enables the drilling of holes and installation of fasteners in ceilings directly by an operator standing on the floor below the ceiling. The arm has a foot-actuated lever, a telescopic pole, and a tool cradle. The power or impact tool is mounted on the tool cradle and is brought into contact with the ceiling by depressing the foot-actuated lever which raises the telescopic pole and thereby the tool cradle. Means for remotely actuating the trigger of the impact tool are also disclosed. |
