摘要: An improved corner finishing tool for applying mastic along a wall joint and having container that defines cavity open in two convergent substantially perpendicular planes, said being bordered by surfaces converge peripherally of cavity, means comprising pair rigid retainer plates joined together spring loaded hinges or fasteners biased to position resilient flex. A lever arms pivotally secured an edge portion the at one end are acted upon leaf springs which engage selected positions relative pivotal connection adjusting flex between plates. Mastic material is fed into through socket bracket mounted there also alignment wheel.
