This video demonstrates how to install Garvin Industries’ 4″ square junction box. A standard four inch square junction box is needed to hold electrical connections, terminations, and electrical devices on covers. They also are needed to provide a safe, secure enclosure. These boxes are available in a variety of depths ranging from three and a half inches to one and a quarter inches. Boxes with a clamp are also available. All boxes come standard with a knock out. Knock outs come in various sizes and are used for the entry of a conduit or cable to connect or terminate wiring inside a box.
