Conduit

Also known as FMC, this conduit offers the crush resistance of metal combined with flexibility to handle bends in tight spaces.

Zinc-plated steel conduit has a heavy zinc coating for corrosion resistance. Aluminum conduit is lighter than steel and has good corrosion resistance. It's often used to hook up motors and light fixtures.
