Orbit 4SB-MC-MS 4 in Square Electrical Box 1-1/2 in Deep

Product Description

The ORBIT 4SB-MC-MS is a 4-inch square electrical junction box with a 1-1/2 inch depth, designed for use in commercial and residential wiring applications. This box provides a sturdy enclosure for splicing conductors, mounting wiring devices, or housing low-voltage connections. Electricians rely on square boxes of this type when standard single-gang boxes do not offer enough interior volume for conductor fill compliance under NEC guidelines. The 4-inch square form factor is one of the most common in the trade, accommodating a wide range of covers and device rings.

This box is suited for installation in new construction and retrofit projects where conductors must be housed in a code-compliant enclosure. It is typically mounted to studs, joists, or structural framing in wall or ceiling applications. The 1-1/2 inch depth provides adequate cubic inch capacity for multiple conductors and devices without requiring a deeper box in standard installations.

Key Features

• 4-inch square footprint fits standard square covers and plaster rings
• 1-1/2 inch depth supports NEC conductor fill requirements in typical wiring runs
• Compatible with common device rings for single-gang, duplex, or blank cover configurations
• Suitable for new construction and retrofit electrical rough-in work

Compatibility

Designed as an OEM-style replacement or new-installation 4-inch square electrical box compatible with standard square box covers, mud rings, and extension rings used in residential and commercial wiring applications.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. De-energize the circuit at the breaker panel and verify absence of voltage before working inside any enclosure. Secure the box firmly to framing before pulling conductors, and ensure conductor fill does not exceed the calculated cubic inch capacity per NEC Article 314.
