Orbit CB-B 4 Inch Octagon Concrete Ceiling Box Ring

Product Description

The ORBIT CB-B is a 4-inch octagon concrete ceiling box ring designed for use in concrete ceiling installations. This ring serves as a mounting extension or retrofit adapter, allowing electricians to bring an existing or newly embedded octagon box flush with the finished ceiling surface. It is a standard trade accessory used in commercial and residential concrete construction where recessed electrical boxes require a surface-level transition ring to support fixtures, covers, or junction box covers properly.

This ring is suited for concrete slab ceiling applications commonly found in commercial buildings, multi-family residential units, and any structure where electrical boxes are cast into or anchored within a concrete ceiling. It provides the necessary extension to align the box opening with the finished ceiling plane, making it a practical component during rough-in and finish electrical work in concrete construction.

• 4-inch octagon profile matches standard octagon box dimensions for direct fitment
• Designed for concrete ceiling installations requiring box-to-surface alignment
• Functions as a retrofit ring to bring recessed boxes flush with finished ceilings

Installation Notes

Installation should be performed by a licensed electrician in accordance with applicable NEC requirements. De-energize all circuits at the breaker panel before working on or near the electrical box. Ensure the ring seats flush against the concrete surface before securing any fixture or cover plate. Verify local code requirements for box fill and cover plate fastening in concrete ceiling assemblies.
