RACO 674 16.5 cu in handy box

The RACO 674 is a single-gang handy box designed for electrical installations requiring a 16.5 cubic inch capacity. Its galvanized zinc coating protects the steel body from corrosion in damp or outdoor locations. Electricians and maintenance crews use it to house switches, receptacles or wiring splices in surface-mounted runs.

Sustained load performance

The steel construction maintains structural rigidity when multiple conductors fill the 16.5 cu in volume, preventing deformation during wire pulls. Two 3/4-inch back knockouts and six 3/4-inch side knockouts provide consistent entry points without the need for field drilling. UL listing confirms the box meets safety standards for continuous service in approved wiring systems.

Thermals noise and power

As a passive metal enclosure the box generates no heat, noise or electrical draw of its own. The galvanized finish dissipates any warmth from connected devices through the steel walls. Nominal dimensions of 4 inches by 2 inches by 2 1/8 inches allow it to fit standard handy-box covers and mounting hardware without modification.

Questions about this item

Does the steel box dissipate heat well when circuits run all day?

The galvanized steel body conducts heat away from wiring, and the 16.5 cu in capacity gives conductors room to stay cooler during continuous loads.

What mounting hardware must I already have to install this 1-gang box?

You need screws or bolts suited to the surface you are mounting to; the box itself has no integral bracket.

Will the two 3/4 in. back knockouts and six side knockouts line up with my existing conduit?

Yes, the eight 3/4 in. knockouts accept standard conduit fittings for extending older raceway systems.
