15.5 cu in aluminum device box

The Killark FXB-6 is a single-gang electrical box rated for hazardous locations. Its aluminum construction provides durability in demanding industrial or commercial environments. The gray finish aligns with standard conduit systems. It is suited for electricians and facility managers needing a listed enclosure for device mounting.

Two opposing hubs with lug brackets

The box features two hubs positioned on opposite sides, each supplied with lug brackets for secure conduit attachment. This layout supports straight-through wiring runs without extra fittings. CSA and UL listings confirm compliance with North American safety standards for hazardous-area installations.

Aluminum body resists corrosion

The aluminum material withstands moisture and chemical exposure better than standard steel boxes. Lug brackets simplify mounting to structural surfaces while maintaining grounding continuity. The 15.5 cubic inch capacity accommodates standard switches or receptacles with adequate wiring space.

Questions about this item

Will the aluminum lugs or clamps need periodic tightening or replacement?

The box uses fixed aluminum lugs for mounting and has no clamps; the lugs are integral to the body and do not require routine tightening or replacement.

What is the practical fill limit when the box is used continuously with multiple conductors?

The internal volume is 15.5 cu in; conductor fill must follow the rated cubic-inch capacity for the wire gauge and device count installed.

Does the aluminum body run hot or create electrical noise when energised all day?

Aluminum dissipates heat effectively and the enclosure is passive; it produces no electrical noise and operates at ambient temperature under normal load.
