The world's first cage clamp NEMA wiring device wins the 2007 ESTA Dealer's Choice Awards Expendable Product of the Year!

Since their invention in the late 1800s, virtually all electrical wiring devices have had one common feature: the screw type terminal.
Although screw terminations are functional they do have a flaw: screw terminals loosen. Screw terminals may loosen due to vibration from motors or transport. After screw termination is made, the fine copper strands tend to shift, allowing the screw to loosen. This phenomenon is called "creep." It leads to heat rise, more loosening, and often device failure. Screw terminals also loosen because they are not tight enough in the first place. Unless you use a torque-measuring screwdriver, it is nearly impossible to know if you are making a proper termination.

Enter Lex-Loc!

The cage clamp terminals are based on the concept of using spring pressure instead of screws to make the termination. The spring delivers a pre-determined amount of pressure and automatically adjusts to shifting strands (creep). This revolutionary design utilizes color coded cam levers to open and close the chambers that accept the conductors. Users simply strip the conductor using the gauge on the device, open the terminal by hand, insert the conductor and close the lever.
