A fastener actuation system for driving fasteners into a work surface separated a significant distance from a user, the system comprising a fastener actuation tool coupled to a pole assembly, the assembly including a lockout mechanism disposed within the tool. The tool may have a firing pin assembly configured such that depression of the barrel assembly against the work surface loads a firing pin into a ready-to-fire position. In addition, the tool may have a trigger sleeve slidable within the tool housing and having a ramp surface such that forward motion of the trigger sleeve may cause a trigger sear to move along the ramp surface until a point where the sear disengages and the firing pin fires. The lockout mechanism may include a ball and a receptacle, where the receptacle receives the ball if the tool is in an acceptable orientation and does not receive the ball otherwise. |
