Welcome to the Thermo Cube® website

The Thermo Cube® is a unique temperature controlled electrical device. It operates with any 15 amp 120 volt electric heater or fan and plugs directly into a standard outlet. It is thermostatically controlled and turns the power on and off automatically, according to outside ambient air temperature. Best of all it saves money by using power only when the temperatures require.

The Cord Connect™ is a simple, practical and effective patented cord lock. Includes a "clamshell' design that enables you to simply close the cord lock around each end of the cord, and then twist to lock the cords together. The Cord Connect will provide a secure, water-tight connection for extension cords outdoors. Run cords in out of the way, hard to reach places without worry of being disconnected. The Cord Connect will lock the connection while keeping it water-tight for worry free power.
