Condu-lok , the evolution of fitting tube

[pirate]

I watched an American video recently about wiring a shed, which, according to local codes, needed the wiring to be in steel conduit, albeit it was installed behind the drywall finish. The guy used a similar system, but with screws with a slotted head rather than a grub screw. I feel a grub is better, more secure.
For fun, I simply mention that steel tube secured by grub screws has been a thing...though not for electrical work, for decades. I started using it 50 years ago, and most recently 6 months ago to install safety rails around a building, with, I think, 50mm tube. Threading those would have been a tricky job, but we used Kee Klamps, same as I used 50 years ago, and same as installed throughout your town centre as railings at pedestrian crossings etc. I love 'em!

I can see the advantages of this especially if your adding to and existing system, but I really don't see that much of an issue with threading.
I had to do some Galv the other day and threading it was effortless, that was using a cheap TLC stock and die set too.

I turn up and use whatever is supplied. If it needs threading, then it'll be threaded, and if its conlok it'll be fixed with a grub screw. Most important factor is that I get paid.

Its a good product if used correctly . Bit of CT1 etc will keep the weather out . Do guys use PTF tape on threaded to stop water etc coming in ??

PTF's for keeping the water IN......not too good for earth continuity..........although, if there's no earth fault there's no leakage either way, I suppose.
