Single-gang FD device box

The Hubbell Killark FD-1 is a single-gang aluminum device box with a 47.0 cu in capacity. It is intended for electrical installations that require a durable, corrosion-resistant enclosure for switches or receptacles. The gray finish suits industrial and commercial environments. An internal grounding screw is included for equipment bonding.

Verify conduit and mounting compatibility

Confirm that your conduit system uses 1/2 in tapered threads to match the single inlet hub. The box measures 4.56 in by 4.56 in with a 2.0 in depth, so ensure the installation cavity accommodates these dimensions. Mounting holes are spaced 0.5 in on centre; check that your surface or bracket aligns with this pattern before ordering.

Upgrade from non-metallic or smaller-capacity boxes

This aluminum box replaces plastic or smaller metal enclosures when greater wire-fill capacity and mechanical protection are needed. The 47.0 cu in volume eases conductor routing in heavy-duty circuits. The jump is worth it for wet or corrosive locations where aluminum outperforms non-metallic alternatives.

Questions about this item

What comes with the FD-1 device box and what must I buy separately?

The box includes the aluminum FD-1 body with a 1/2 in hub, internal grounding screw, tapered threads and mounting holes on .5 in centres; you will need to supply a cover, gasket and any conduit fittings separately.

How do I decide between the available capacities for this box?

This FD-1 model is offered only in a 47.0 cu in capacity, so there is no alternative volume to choose from.

What does the 47.0 cu in capacity mean when the box is installed?

It provides 47.0 cubic inches of internal wiring space within the 4.56 in by 4.56 in by 2.0 in aluminum enclosure, determining how many conductors and devices the box can legally contain.
