55082121 25-Feet 1/2-Inch Alflex-Type RWA Reduced Wall Aluminum Flexible Metal Conduit

For some reason the big box stores don't have enough choices in aluminum flex. Happy to see it available at Amazon for a better price.

I have used this for external cat 5E runs and and it worked very good and it's very durable very durable and gotta love how flexible it is

Good quality, light, unbeatable price (1/2 of the big orange box store!) Very easy to snake, even my bulky bundle of 3 #8 wires went through quickly.

Used to protect 240v 10-2 wire for a 6kW heater and a 7kW solar system. Easy to pull the wires through and cut with a portaband saw. Note : it is covered in oil.

My bunny chews right through plastic cable covers, so I decided to give this a try to protect the cable to the new litter box. It arrived very very dirty, like filthy and greasy, but I cleaned the outside off and resolved not to think about the inside. So far bunny is not chewing on this metal tube.
