Aluminum Conduit/Fittings are a protective pipe or tube through which electric wires or cables are run. It makes an excellent choice for home decor projects. It can be easily cut, threaded, and bent without using special tools. It resists corrosion and does not leave discoloring streaks or stains. It is used to sheath electrical wires. It is used to retrofit for tunnels because the aluminum is light enough to handle, and it does not rust in hard weather. It is mainly used where weight is required to be minimized.
