The 39092 provides a set of two 12 in. by 1.26 in. wiring ducts with covers for use inside our enclosures. Wiring ducts with covers enable you to route cables and wires into specific areas within an enclosure to help keep the inside of your enclosure neat and tidy. This benefit not only improves the appearance of your enclosure, but it also prevents wires from touching areas they shouldn't and makes maintenance, modifications, and troubleshooting easier later. For a single set of the wiring duct with cover, see the 28517 product page.
