Abb 270RAC 4-inch Octagon 2D Concrete Ring

Product Description

The ABB 270RAC is a 4-inch octagonal 2-depth concrete ring extension used in electrical rough-in applications. This type of concrete ring mounts over a standard 4-inch octagon box to extend the box depth flush with a concrete pour or masonry surface, giving electricians the clearance needed before the finish cover is installed. The part is sold in carton quantities of 25 units, making it well-suited for commercial or multi-unit residential projects where large quantities are needed at rough-in stage. The carton ships at 13.3 pounds total.

Concrete ring extensions like the 270RAC are used by licensed electricians in new construction where electrical boxes must be set prior to a concrete pour or thick plaster coat. Common applications include poured concrete walls, concrete ceilings, and block construction where standard box depth is insufficient. This ring is appropriate for both commercial and residential installations that require a 4-inch octagonal footprint at the rough-in stage.

Key Features

• 4-inch octagonal footprint matches standard 4-inch octagon box layout
• 2-depth extension ring for added clearance in concrete or masonry pours
• Sold 25 units per carton, reducing procurement steps on larger jobs
• Compact carton dimensions allow straightforward jobsite storage and staging

Compatibility

Designed as an OEM-style extension for use with standard 4-inch octagonal electrical boxes in concrete or masonry installations.

Installation Notes

Installation is performed by a licensed electrician in accordance with NEC requirements for box fill and device support. Power must be confirmed off and the circuit de-energized before any box or extension ring work is performed. The ring should be secured to the box before the concrete pour or wall application begins to prevent shifting. Do not install the cover plate or device until the surrounding surface is fully cured and the box is confirmed plumb and flush.
