Garvin 54151-OWBX 4" Octagon Old Work Cut-In Box, 1-1/2" Deep, BX Clamps

1-1/2 in deep 4 in old work cut in octagon boxes are used to add outlets and other devices to existing walls using EMT conduits or 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.
