Abb 52C33/4 4 Inch Square Plastic Outlet Box Ring

Product Description

The ABB 52C33/4 is a 4-inch square, 3/4-inch deep plastic extension ring designed to add depth to standard 4-inch square electrical outlet boxes. This device ring is used to increase the usable wiring space inside an outlet box assembly, accommodating additional conductors, devices, or splices where code compliance requires more cubic-inch capacity. Electricians install this ring between the box and the cover plate or mud ring to meet NEC fill requirements. It is a common component in commercial and residential rough-in and trim-out work.

This extension ring is suited for use in standard 4-inch square box installations in both new construction and retrofit applications. It fits over an existing 4-inch square box to extend the depth without replacing the box. Typical applications include gang device installations, junction box expansions, and service upgrades where box fill calculations require additional volume.

Key Features

• 4-inch square footprint matches standard 4-inch square outlet boxes
• 3/4-inch depth adds cubic-inch capacity for NEC box fill compliance
• Plastic construction for lightweight handling and corrosion resistance
• Sold in carton quantities of 25 for job-site efficiency

Compatibility

Designed as an OEM-style extension ring for use with standard 4-inch square electrical outlet boxes in residential and commercial wiring installations.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC). De-energize the circuit at the breaker panel and verify with a non-contact voltage tester before handling any wiring or box components. Secure the ring to the box using appropriate fasteners and confirm all conductors are properly dressed before installing the device or cover plate.
