1-1/2" deep, 3-1/2" octagon boxes with old work ears and clamps for nonmetallic sheathed cables are used when installing ceiling or wall lighting fixtures. Old work “cut in” boxes with ears allow for an easy addition of outlets and fixtures in existing walls and ceilings. Garvin Industries’ octagon boxes are made with a versatile combination head 8-32 screw. These octagon boxes allow economical box installation when minimum wire capacity is required.
