Orbit D4SB-75 4 Inch Square Electrical Box 1-1/2 Deep

Product Description

The ORBIT D4SB-75 is a 4-inch square electrical junction box with a 1-1/2 inch depth, designed for use in residential and light commercial wiring installations. This type of square box provides interior volume for wire splices, device mounting, and conduit terminations where a standard single-gang box does not offer enough capacity. Electricians use square boxes with cover plates or mud rings to adapt to a wide range of outlet, switch, and blank cover configurations. The box is a standard trade size that fits common rough-in and retrofit applications.

The D4SB-75 is suited for new construction and remodel wiring projects where a 4-inch square box is specified. It accommodates multiple knockouts for conduit entry and is appropriate for use in walls, ceilings, and exposed conduit runs. Installation follows standard electrical rough-in practices and applies to circuits wired under the National Electrical Code (NEC). Compatible cover plates, extension rings, and mud rings for 4-inch square boxes are widely available from multiple manufacturers.

Key Features

• 4-inch square footprint provides generous interior volume for multi-conductor splice points
• 1-1/2 inch depth suits standard wall and ceiling rough-in applications
• Standard 4-inch square format accepts common mud rings, raised covers, and extension rings
• Multiple knockout configurations support flexible conduit or cable entry routing

Compatibility

Designed as a standard 4-inch square, 1-1/2 inch deep electrical box for use with NEC-compliant wiring installations. Compatible with standard 4-inch square cover plates, mud rings, and extension rings available from most electrical supply manufacturers.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code and applicable local codes. De-energize the circuit at the breaker panel and verify with a non-contact voltage tester before working inside the box. Secure the box to structural framing or approved mounting hardware before pulling conductors. Do not overfill the box beyond the calculated conductor fill capacity as defined by NEC Article 314.
