A device for securing a corner bead to a first and a second wall which define a corner in a room of a structure. The device includes a powered impact tool having an operative end with a crimping unit adapted to be secured to the operative end. The crimping unit includes a housing in which a claw assembly is disposed. The claw assembly includes at least a pair of arms each having a claw edge for piercing the corner bead. The claws are positioned opposite one another in the housing. The arms have a first, inoperative position and a second operative position such that when the impact tool is actuated, the arms move between the first position and the second position, so the claw edges contemporaneously pierce the corner bead and the first and second walls. |
