i have a 25' ceiling in a warehouse and i need to drop 1/2" EMT from the ceiling to the floor to power a drill press. There are no walls or vertical beams anywhere near the drill press location.....:-?

I dont think rigid gets you out of strapping. You could fish MC down some EMT and that is called a wallthats what I thought.. the rigid idea makes sense but couldnt find a way around strapping.. strut makes the job too costly considering i have multiple location drops.. thank you

Problem to cord pedants is subject to miss use. Legal but prefer not to use if it is fixed location. Seen at at 1 not to be named factory that had hundreds of them. Coiled up at ceiling when not needed. Needs changed every week. Many unused lay there for years.too costly compared to what? No strapping at all is least cost but we are talking about what to strap to. Strut is relatively inexpensive compared to other possibilities of what you could put there to strap to. It may be kind of flimsy if it spans 25 feet but will be cheaper than something that is not flimsy that spans this far.
I would suggest cord pendants.

Would you rather see a properly installed cord pendant or see the end user tie up extension cord from wherever he seen as convenient (maybe even an adapter screwed into a lampholder) and drop down to where power is needed.
Anything can be misused.
What needs changed every week?
Coiled up at ceiling when not used is away from physical abuse that may exist if laying on floor when not in use. Coiled up in ceiling would be a problem.
Laying there unused for years I don't see as much of a hazard, The ones being used will get wear and tear on them. Unused ones that lay there for long time may get brittle but generally will not crack until they are flexed when someone does decide to do something with them.

too costly (labor and material) for the purpose of the job. Customer can do without if its not cost effective. Theres 4 different locations to drop electrical in a proposed new layout of an existing shop. but its going to work out with 20' rigid drop and 6' strut ground up, then finish with EMT ...cord pendants? s/o cords from 25' ceiling?
Why not use one-hole strap to floor equipment? Why bother with ground-up strut if not required?its going to work out with 20' rigid drop and 6' strut ground up.. from 25' ceiling?
Brilliant, especially w/ Caddy straps rather than strut.stew said:drop some 3/8 all thread with a coupling down from above and mount a couple of short pieces of strut..
