ABSTRACT:
A generally polygonal block-like enclosure of rigid material including a top and bottom wall, a pair of a concave inward front walls which define an inner corner adapted to fit on an outside corner, and a back wall spaced from the front walls by a pair of spaced side wall. The back wall includes a centrally disposed spherical cavity sized for receiving a bail socket connector which is preferably retained therein by a spring clip or equivalent retaining means and each front wall includes a vertically oriented channel which extend between the top and bottom walls. The enclosure also includes a manifold which connects the spherical cavity in the back wall to each of the channels in the front wall. In operation, a pump-type applicator is connected to the ball socket connector and is operated to direct a regulated flow of mastic material to the spherical cavity which, in turn, is directed through the manifold to the vertical channels of the front walls for simultaneous deposition of a bead of mastic material along each of the two adjoining wall board sections as the tool is moved in the vertical direction along the outside corner.
