Aluminum Flexible Metal Conduit are produced from aluminum or steel by coiling a self-interlock ribbed strip of this metal. This creates a tube. The diameter of the tube may change and different finish applications demand different diameter tubes. Wires are pulled through this tube and are therefore protected from harm, both external and internal.
The Flexible Metal Conduits will bend to match your setup program. Unlike rigid conduits in which you have to manually bend the conduit into a predetermined position or purchase a pre-bent conduit, the Flexible Conduit can alter its shape as you set up as well as repairs or adjustments will need to be made. The term flexible in its title can reference its ability to bend in a specific position, but it also may reference the flexibility it provides in your setup.
