Orbit Industries 3PB Round Ceiling Pancake Box 3.9 Cu in

Product Description

The ORBIT INDUSTRIES 3PB is a round ceiling pancake electrical box designed for flush-mount ceiling installations in residential and commercial wiring applications. Constructed from 16-gauge sheet steel, this box provides a rigid, code-appropriate enclosure for ceiling fixture connections. It features a 3.9 cubic inch interior capacity and includes multiple knockout configurations: three 1/2-inch knockouts, four 1/2-inch circular pryouts, and three 3/8-inch knockouts, giving installers flexible conduit and cable entry options. The low-profile pancake design keeps the box tight to the ceiling surface, making it a standard choice for light fixtures, fans, and similar ceiling-mounted loads.

This box is suited for residential and light commercial wiring installations where a shallow, surface-hugging enclosure is required. Typical applications include ceiling junction points for lighting fixtures and paddle fans mounted directly to structural members. The round 3-1/4-inch diameter footprint fits standard ceiling cutouts and joist-mount scenarios. Electricians working on new construction or retrofit projects will find the knockout layout accommodates both NM cable and conduit entry.

Compatibility

Designed as an OEM-style replacement and standard new-work ceiling pancake box for residential and commercial electrical fixture installations requiring a round, shallow steel enclosure.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize the circuit at the breaker panel and verify the circuit is dead with a voltage tester before beginning work. Secure the box to a structural ceiling member capable of supporting the intended fixture load. Do not exceed the box fill capacity calculated per NEC Article 314 for conductors, devices, and fittings installed inside the enclosure.
