EMT is one type of tubing normally used to carry electrical wires. The three types are, from lightest to thickest: Electrical-Mechanical Tubing (EMT), InterMediate-(weight) Tubing (IMT) and Rigid Metal Conduit (RMC). They all have their own standard sizes, which is to say they are not the same as what they’re called. A one-inch EMT is actually more than an 1/8th larger than 1″ on the outside: it’s 1.167″! So….
IMPORTANT: Be sure of the type and diameter you will be attaching to before ordering! Opened packages will not be accepted for return.
EMT is used in picnic and event canopies typically (often due to local regulation) under 8 feet tall, and are great for a wide variety of structures where strength and light weight are both prized. For example, nearly all the photos on this site were taken with my EMT-based technical-photography platform.
HEADS-UP: EMT ≠ Water pipe. If what you’re looking at is a copper water pipe, that’s not EMT, and the sizes are different. We’re working on extensions to the Tubing line to work with copper water pipes like we have in all our houses, but they’re not there yet.
In other uses where you might be running cables around existing–live–EMT runs, make sure the tubing is well secured in place, and be very careful to not put excessive weight on the tubing. As long as you’re being safe about it, 4CELNK-YR will help you run cables where you need them, and change them when you need that.

Again, be very sure about what size you’re getting. Measure it with a caliper if you’re unsure. If you haven’t worked with it before, 1″ conduit looks deceptively like a 1-1/4″ tube, and 3/4″ looks like an suspiciously under-sized 1″. Measure twice, and if that doesn’t work, measure again, but write it down this time. 😉
