A wire duct is an important product, for it helps to not only protect the wiring within, but neatly and safely deliver the wiring to necessary components within and without your building. Wiring ducts come in different forms: from flexible wiring ducts meant to face the extremes of the elements and even fire, metal wiring ducts, and wiring ducts made of non-metal.

Often the leading manufacturers of wiring ducts are also wiring duct suppliers and distributors of wiring ducts. Many of these companies have been in business a long time, and thus have established excellent reputations in their field. Consider these options as you look for the wiring ducts that are best for your business.

1. Choose flexible wiring ducts for the extremes.

2. Use metal wiring ducts for interior and exterior uses.

3. Pick non-metal wiring ducts for other applications.

Action Steps
The best contacts and resources to help you get it done

Depend on flexible wiring ducts that can withstand the extremes of nature

These wiring ducts can be found in underground tunnels and even in water.

I recommend: One leading manufacturer of flexible wiring ducts and tubing that comes to the forefront is Dura-Line. Their flexible wiring ducts work in extreme conditions, such as in laying fiber optic cables beneath city streets, in underground tunnels filled with water, between telephone poles and on power lines. They have a variety of wiring ducts that can withstand crushing loads, gun shot pellets, water infiltration and fire. A company that nicely compliments Dura-Line's product line is Underground Devices, which manufactures "conduit support systems for underground power transmission projects.” The two companies can cover any flexible wiring duct needs.

Pick metal wiring ducts for exterior and interior uses

Metal wiring ducts withstand wind and water. Thanks to their durability, they can be on the outside of your building as will as inside, and you can depend on them to protect the wiring inside.

I recommend: Metal wiring ducts can be made of various materials, including stainless steel, steel, brass, copper, aluminum, bronze and more. Two wiring duct distributors and wiring duct manufacturers of metal wiring ducts are Johnson Brothers and MI-Kee-Tro Metal Manufacturing.

Pick non-metal wiring ducts for other applications

The materials chosen are corrosive and moisture proof.

I recommend: One leading manufacturer of wiring ducts that chooses non-metal when manufacturing their line of wire management system is AutomationDirect. They have wiring ducts made of rigid PVC, which carries a flammability rating. AutomationDirect's wiring ducts come in various sizes. Many include "fingers," which are slots that can allow wires to pass through. The corners of these fingers are round to prevent harmful abrasion. Another leading manufacturer is Niedax-Kleinhuis USA.
