ABSTRACT:
A framing tool is disclosed for applying fasteners to the interior perimeter of a frame to mount a picture or the like. The framing tool includes a conventional fastener applying instrument that includes a driving means for propelling a fastener into the frame and a storage means for storing a plurality of fasteners and delivering the fasteners to the actuator means. An actuator assembly is provided for both positioning and triggering the fastener applying instrument. The actuator assembly includes a rod that communicates with the driving means and is slideably coupled to a sleeve. A backing plate is selectively secured to the sleeve by a clamping arrangement to engage the exterior perimeter of the frame and position the driving means. A trigger is provided that moves the rod relative to the sleeve in order to actuate the driving means.
