RACO 175 4" Octagon NMC Outlet Box, 2-1/8" Deep

RACO 175 4" Octagon NMC Outlet Box, 2-1/8" Deep

The RACO 175 is a 4" octagon outlet box built with a 2-1/8" deep body and an integrated NMC (non-metallic cable) clamp design that secures NM cable entries directly at the box knockouts. Sized to the standard 4" octagon footprint used throughout residential and light commercial branch-circuit wiring, this box is supplied in bulk packs of 100 so contractors and electrical distributors can keep high-volume rough-in projects fully stocked without constant reordering. The RACO 175 follows a familiar, straightforward box style for ceiling fixture, junction, and device applications wherever an octagon footprint is called for, giving electricians a consistent, repeatable box on every run.

Key Features

• Trade Size: 4" octagon body dimension matches standard octagon box openings, ceiling pans, and fixture plates for a clean fit.
• Box Depth: 2-1/8" deep interior provides usable working space for splices, pigtails, and device or fixture connections.
• NMC Clamp Design: Integrated NMC (non-metallic cable) clamps grip NM cable entries directly at the box, reducing the need for separate cable connectors and speeding up rough-in.
• Octagon Configuration: Round/octagon shape is purpose-built for ceiling fixture boxes, general junction points, and applications where a round device or canopy will be installed.
• Bulk Pack Quantity: Sold in packs of 100, simplifying ordering and inventory management for contractors, electricians, and distributors handling large rough-in jobs.
