Review on King Innovation 95015 AlumiConn Connector by Paul Tilden

This is the easiest and most reliable way to connect old aluminum wiring. Simply strip the wire, insert the screw, and torque to specification (10 in-lbs for regular #12 aluminum wire, or about 1 full turn after initial contact). Most of the time I can control the torque required just by holding the connector in my hand, but if it's too uncomfortable you can clamp it with pliers or something similar. but at least they are well packed in the box. You are also limited to three wires per connector. The main problem is of course the price. Whether it's worth (and the CO/ALR devices) replacing the copper cabling depends on your particular circumstances.
