Electrical box for hazardous locations

The Killark SWB-2 is a one-gang device box built from aluminum for use in rated hazardous locations. Its gray finish and lug brackets suit surface-mount wiring in industrial or commercial settings. The box carries CSA and UL listings for code compliance.

22 cu in capacity

Internal volume measures 22 cu in, which determines the maximum conductor fill allowed by code. This single hub opening accepts conduit or cable entry for a straightforward branch-circuit connection.

Fill limits and use cases

The 22 cu in volume comfortably handles typical switching or receptacle devices with a modest number of conductors. Larger multi-wire circuits or devices with internal components may exceed the permitted fill and require a larger box.
