Electrical Box 16.5 cu in

The RACO 670RAC is a galvanised handy box designed for residential and light commercial wiring. Its 16.5 cu. in. capacity accommodates conductors and devices in standard wall cavities. The welded steel body provides structural rigidity for secure mounting. Electricians and contractors use it for single-gang switch or receptacle installations.

Eleven 1/2 in. knockouts

The box is supplied with eleven 1/2 in. knockouts positioned on multiple faces. This arrangement allows conduit or cable entry from several directions without additional drilling. Installers can select only the openings required for the specific circuit layout. The factory-formed knockouts maintain the box's fire-rated integrity when removed correctly.

Welded construction and fire rating

Welded seams create a continuous metal enclosure that resists deformation during installation. The assembly is acceptable for use in 2-hour fire rated walls, meeting code requirements for fire separation. Galvanised coating protects the steel from corrosion in damp locations. The 4 in. x 2 in. footprint fits standard stud bays for straightforward mounting.
