Abb Installation Products 52171 X Square Outlet Box Steel

Product Description

The ABB INSTALLATION PRODUCTS 52171 x is a pre-galvanized steel square outlet box designed for residential and commercial electrical rough-in work. Measuring 4 inches by 4 inches by 2.125 inches deep, it provides 30.3 cubic inches of usable volume, making it suitable for installations requiring larger device or junction capacity. The box ships with an integrated armored cable clamp (C-3) that secures armored cable or metal clad (MC) cable directly at entry. Eleven knockouts are provided, sized at 1/2 inch and 3/4 inch eccentric configurations, giving installers flexibility for conduit or cable routing from multiple directions.

This box is used in both residential and light commercial electrical installations wherever a 4-inch square box is required. It is well suited for junction boxes, device mounting with a raised cover or mud ring, and cable terminations involving armored or metal clad cable. The built-in C-3 clamp eliminates the need for a separate cable connector at the clamp entry point, streamlining rough-in in new construction and remodel work. The pre-galvanized steel finish provides corrosion resistance in standard indoor environments.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize all circuits at the panel before mounting or wiring the box. The integrated C-3 clamp is intended for armored or metal clad cable only — do not use with nonmetallic sheathed cable without an appropriate clamp substitution.
