www.GarvinIndustries.com - 4" Octagon boxes come in 1-1/2", 2-1/8" & 3-1/2" depths and are used in the installation of wall or ceiling lighting fixtures, ceiling fans, security cameras, or various other electrical appliance (OEM) applications. They come in a variety of styles and offer 1/2", 3/4" & 1" knockout configurations. Garvin octagon boxes can be used in old work "cut in" applications or new construction. Fan rated boxes are extra heavy duty and are made to accommodate the vibration of a rotational fan or large chandelier. Dual Ear (DE) boxes are great when the mounting provision on exit signs, security cameras, and emergency lights is fixed in the wrong position. 4" Octagon Extension Rings are 1-1/2" deep and offer 1/2" & 3/4" conduit knockouts. These extension rings are used when extra cubic inch capacity is needed for additional wiring. They are made from rugged galvanized steel. Garvin Industries' labor-saving brackets allow the box to be mounted directly onto structural members and provide an unobstructed path for conduit and cable installation. Garvin Industries electrical box extension rings prevent the labor-intensive removal of older outlet boxes, connectors and devices when extra wire capacity is needed. Adapter slots on the bottoms of extension rings allow an easy, slide-on attachment to existing electrical junction boxes.
