Hubbell manufactures an extensive line of back boxes, each designed to give the user the
maximum amount of wiring room while assuring grounding to metallic conduit. And, you can
depend on Hubbell back box enclosures to perform reliably--even in hostile environments.
Hubbell back boxes are available in nonmetallic as well as metallic. These boxes are
made of cast aluminum, suitable for IP54 requirements, and are finished with enamel paint.
These boxes withstand a 500-hour salt spray test as well as UL raintight and external
icing tests. |
