Abb Installation Products 54171nl Octagon Box 22.5 Cu in

Product Description

The ABB INSTALLATION PRODUCTS 54171nl is a pre-galvanized steel octagon outlet box designed for flush mounting in walls and ceilings in residential and light commercial electrical installations. At 22.5 cubic inches of usable volume, it meets NEC fill requirements for standard wiring configurations. The drawn steel construction provides a rigid, one-piece housing. It ships with non-metallic cable clamps (C-5 style) and an L bracket already installed, making it ready for direct use with non-metallic sheathed cable (NM/Romex-type wiring). Licensed electricians performing rough-in work are the primary installers of this box.

This octagon box is suited for ceiling and wall fixture applications in new construction and retrofit projects where non-metallic sheathed cable is the wiring method. The included L bracket supports mounting to framing members, and the 1/2 inch knockouts accommodate standard conduit connectors or cable entry points. The 4 inch diameter footprint is a common standard size for ceiling-mounted light fixtures and junction points in residential branch-circuit wiring.
