ABSTRACT:
A combination tool for the installation of wallboard and the application of insulation to a building. The tool comprises an elongate, rectangular, tublar rod having a kickjack at one end and an extender, which is attachable to the kickjack and is used for adjusting the length of the tool. The tool performs two functions as a wallboard installation device. First, a blade at the free end of the kickjack is used for supporting wallboard as it is being positioned and secured to a building frame, thereby freeing the construction worker's hands so that only one worker is required to hang a piece of wallboard. Second, the tool is useful as a "kickjack" or lever-fulcrum combination to install a wallboard at floor level tightly against an upper level wallboard. The combination tool also has a tined attachment, which can be fixed to the blade, for applying insulation to a building frame.
