1-1/2 in deep 4 in octagon boxes with clamps for nonmetallic sheathed cables are installed in walls and ceilings for lighting fixtures and other outlet devices that are powered using nonmetallic sheathed cables. Garvin' cable clamps save both time and money by allowing the nonmetallic sheathed cables to be easily terminated in boxes without the need for costly external box connectors. The various mounting brackets allow easy box positioning along studs or joists.
