Hubbell Ceil Box 4 Round Ceiling Box Nail Mount Nm

Product Description

The HUBBELL CEIL BOX 4 is a 4-inch round ceiling electrical box designed for nail-mount installation in new construction and retrofit framing applications. It mounts directly to wood framing members using nails, making it well suited for overhead fixture rough-in work. Electricians use this box as the primary mounting point for ceiling fans, light fixtures, and similar ceiling-mounted loads. The round profile and NM (nail-mount) design allow for fast, secure placement during the framing stage before drywall is hung.

This ceiling box is intended for residential and light commercial electrical installations where a round overhead box is required. It is commonly installed in wood-frame ceilings during rough-in to support junction and fixture connections. The nail-mount design eliminates the need for separate mounting hardware in standard stud framing, streamlining the rough-in process for electricians working on new construction or framed additions.

Key Features

• 4-inch round profile sized for standard ceiling fixture and fan mounting
• Nail-mount (NM) design for direct attachment to wood framing members
• Suitable for ceiling junction and fixture wiring applications
• Streamlines rough-in by integrating mounting directly into the box
• Compatible with standard round cover plates and ceiling fixture canopies

Compatibility

Designed as an OEM-style replacement or new-install ceiling box for standard residential and light commercial wood-frame construction requiring a 4-inch round nail-mount overhead electrical box.

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 before any wiring connections are made. Nail the box securely to the framing member so it sits flush with the finished ceiling surface, accounting for drywall thickness. Do not exceed the box fill capacity when routing conductors, and verify the box is rated for the fixture weight being supported.
