Orbit Industries 4RBCK Octagon Box Steel Cover Flat

Product Description

The ORBIT INDUSTRIES 4RBCK is a flat steel cover designed for 4-inch octagonal electrical boxes. It features a 0.5-inch knockout, providing a clean entry point for conduit or cable connectors. This type of cover is used to cap, protect, or provide access to junction or device wiring in residential and light commercial electrical installations. Electricians install it as part of rough-in or finish work wherever a 4-inch octagon box requires a flat cover plate. The steel construction provides durable protection and meets standard box cover requirements in common wiring applications.

The 4RBCK is suited for use with standard 4-inch octagonal electrical boxes in residential and light commercial settings. Typical applications include junction box finishing, device mounting support, and conduit entry points in wall, ceiling, and floor box installations. The flat profile keeps the cover flush against the box face, making it appropriate for installations where a raised or extension ring is not needed.

Key Features

• Flat profile for flush mounting on 4-inch octagonal electrical boxes
• 0.5-inch knockout for conduit or connector entry
• Steel construction for durability and standard code compliance

Compatibility

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 and verify with a voltage tester before opening any junction box. Secure the cover to the box using the appropriate machine screws for the box mounting holes. Do not force the knockout; use a proper knockout punch or screwdriver and hammer to remove it cleanly before installing a connector.
