Barton Square Galvanized Back Box With Knockouts, BTSQ10, 4 Inch Height x 4 Inch Width x 2-1/8 Inch Depth

Features

• Robust galvanized steel construction: The back box is formed from steel with a galvanized (zinc-coated) finish, which gives excellent resistance to rust, corrosion and ensures long life even in damp or industrial environments
• Multiple knockouts for wiring flexibility: The unit is supplied with pre-formed “knockouts” (partial perforations) on its sides or base so that conduit or cable entries can be made easily without damaging the box
• Galvanized finish ensures compatibility with conduit systems: Because the box is galvanized, it matches well with other galvanized or steel conduits/fittings in systems where continuity, grounding and mechanical strength are key
• Flush-mount or surface installation capable: The design accommodates both flush mounting into walls and surface mounting when needed, giving the installer flexibility in different building/retrofit scenarios
• There is room to accommodate device bodies, splicing, wiring bend radius, and securing devices to the box without crowding, which is vital for safety, code compliance and ease of maintenance
• While the specification sheet for this exact model may not explicitly list it, typically back boxes from Barton include or allow for a grounding lug or terminal, ensuring an earth path for the metal box in metallic wiring systems
• The box is designed to accept standard switches/outlets and related hardware (screws, mounting tabs), making it easy to integrate with commonly available devices
