ABSTRACT:
A handheld tool for installing flexible metal ties includes a gun-shaped housing having a grip and a barrel portion. When a trigger adjacent the grip is squeezed, a tensioning and cutoff mechanism in the barrel tensions the tie and cuts it off after a predetermined tension is achieved. In order to achieve the substantially higher tensions that are desirable in metal, rather than plastic, ties, the barrel portion of the housing is reinforced with a member that surrounds the forward portion of the barrel portion. The reinforcing member is preferably formed of a rigid member and stiffens the barrel portion of the housing to enable it to resist the tensioning forces applied to the metal tie by the tensioning and cutoff mechanism.
