Pass Through Driver

When Electricians use MC (metal clad)/flexible armored cables to install an electrical box, the cables must be attached to the box using cable connectors. MC cable screw-in connectors are very difficult to physically insert into MC cable and there is no tool specifically designed to accomplish this task. Instead, Electricians need to insert these screws by hand or use a common wrench while simultaneously pushing on the screw. Other connector types are more expensive and risk damaging cable wires. The present invention is specifically designed to quickly and easily insert MC cable screw-in connectors. With a hex shaped well to fit standard MC cable screw-in connectors and a hollow handle, any length of electrical wire may be passed through the core of the tool so that the tool can be positioned to screw the connectors into the MC cable. While ideal for electrical applications as described above, the ability to pass material through the hollow handle while providing a driving action is not limited to electrical applications. 1. The Pass Through Driver will allow Electricians to more easily install the screw-in connectors when attaching MC or Armored cable to electrical boxes. When Electricians use MC (metal clad)/flexible armored cables to install an electrical box, the cables must be attached to the box using cable connectors. MC cable screw-in connectors are very difficult to physically insert into MC cable because the tolerance between the screw and cable is very tight. Electricians need to insert these by hand or use a common wrench. However, the force required to insert the screw-in connector into the metal cable housing is significant and requires both twisting action as well as driving action. Applying this force by hand can quickly lead to fatigue or injury. While use of a wrench provides the twisting action, it does not easily support the simultaneous driving force required to fully insert the screw-in connector.Because of this difficulty installing MC cable ...
