4 in Octagon old work cut in boxes are used to add outlets and other devices to existing hollow walls and ceilings using flexible metal cables. Garvin' cable clamps save both time and money by allowing the flexible metal conduits 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.
