Hubbell Killark SWB-5 Aluminum Feed-Thru Device Box, 3/4 Inch Hubs

The Hubbell Killark SWB-5 is a robust, aluminum feed-through device box designed for hazardous environments, providing safe housing for electrical receptacles, switches, or other devices in classified locations. This single-gang box features two 3/4-inch threaded hubs for conduit entry, enabling easy feed-through wiring configurations. It is certified for use in Class I, Division 1 and 2, Groups C and D; Class II, Division 1 and 2, Groups E, F, and G; and Class III hazardous areas, making it ideal for industrial applications such as petrochemical plants, refineries, and grain handling facilities where explosive gases, dusts, or fibers may be present. Key benefits include its corrosion-resistant copper-free aluminum construction, which offers durability and lightweight handling compared to steel alternatives, reducing installation time and costs. The box supports wet location use when paired with appropriate covers and gaskets, ensuring weatherproof performance. Drawbacks may include higher initial cost over non-hazardous boxes and the need for compatible accessories. Compared to similar products like Crouse-Hinds or Appleton boxes, the SWB-5 stands out with its precise machining for secure fits and Hubbell's reputation for reliability, offering superior sealing and ease of maintenance in demanding settings.
