This handy device allows an installer to punch-down a tool-less jack automatically thereby saving wear and tear on their fingers. The pre-wired jack is placed in the tool and the tool is "opened." This creates the torque necessary to punch-down the IDC blades into the wires and "click" the wire guide into place on the back of the jack. This can be done by hand but causes wear and tear on fingers, especially if many terminations are being done at once. This device saves the wear on the installer's fingers and creates consistent terminations. Recommended to be used if more than a handful of parts are being terminated at once. Works with all L-com RJTL and ECFRJTL style Keystone jacks. Add it to your tool-kit today.
