Single-Gang Electrical Box

The Killark FXB-1 is a one-gang aluminium device box rated for hazardous locations. It provides 15.5 cu in of internal volume for wiring devices in industrial or commercial settings. The grey enclosure carries CSA and UL listings for code compliance.

Replaces Smaller Non-Hazardous Boxes

Upgrading from a standard non-rated box is warranted when the installation area is classified as hazardous. The aluminium construction and lug brackets suit surface-mount conduit runs where plastic or unlisted metal boxes would not meet safety standards.

15.5 cu in Capacity for Limited Device Counts

The cubic-inch capacity comfortably accommodates a single switch or receptacle with a modest number of conductors. It runs out of space quickly when multiple devices, large connectors or extensive splices are required in the same enclosure.

Questions about this item

What size opening does the 15.5 cu in aluminum box need for the single hub?

The box has one hub opening sized for standard conduit entry; match the conduit trade size to the hub when cutting the mounting surface.

How do the integral lugs secure the box, and what step is often missed?

The cast aluminum lugs fasten directly to the mounting structure; the step often missed is tightening each lug evenly so the gray box sits flush without twisting.

Which parts of the CSA and UL listed box need periodic inspection in hazardous locations?

Inspect the aluminum body, hub threads, and lug fasteners for corrosion or damage; replace the entire 1-gang device box if any component shows degradation.
