Hi, for future use, All threads should be 2 full threads past the nut to ensure full engagement. We've had various lock nuts back off and fall off, so now specify nyloc nuts and nordloc washers as standard in any possible locations where vibration from equipment, buildings, wind ect are possible. Just something to think for future installs.
Thanks for this video! Nice to see some of the less publicized parts of electrical installation work - it's not all about pulling wire and connections!
EXCELLENT video, Mike!! 👍 More tutorial videos like this please. This will seriously help the newbies coming into the trade and bring standards back up to what they should be. I love the style of your videos too, very unique and great to watch! 👌 Nice to see quality sparks doing a top job and representing our trade! Keep up the great work! Still hoping to bump into you on-site one day! 😅
@@residualelectrical Yes to be fair the times I've mainly used swivels has been holding up pretty small-size containment, generally for lighting and the cabling for it.
Brings back memories of when I worked for a company called HALSION LTD for Laing o Rourke worked on a NHS building doing just containment and unistrut cutting tons of it as you say so many different ways of doing containment! We were very thorough with galv spraying the ends and end caps etc…doing the risers in the stairwells and box trunking was ok but a bit repetitive as there was so much of it! Your doing well your working for yourself so your getting big bucks at that time I was an apprentice doing all the donkey work so was earning peanuts haha much better when your running your own company!
Great video/tutorial Mike. Really enjoyed the style and content. Just like the good old days, As a side note. Worth looking at Spring washer after a normal washer and Nyloc nuts as well. They will help stop any lossening from vibration but it does mean the cost of project increases. There is a caveat with Nyloc, they are less effective if there is temp cycle from hot to cold on a regular basis. I will try and find you a link to a guy who explains it better than me. Anyway, great content as always Mike.
How come all cable trays that we see British sparks use are suspended like this? In Sweden we use supports that goes up from the middle of the tray or ladder. That brackets gives us the ability to lay the cable up instead of necessarily having to pull it through all those brackets that you use.
I assume this refers to brackets like the 'Legrand OH150PG Overhead Hanger'. They are available and sometimes used in Britain but not supper commen. Partly due to cost and partly due to the British mentality of not valuing comfort over skills and tradition.. "Don't fix it if it isn't broken. We've always done it like that" 👍
You bent the perling.......not just the rod. Obviously these rods are not designed to be bent, and doing so reducing the strength properties.....but I'd be more concerned about the roof. I wonder if the roofing structure is designed to withstand kinks every meter or so?
You can bend rods, seen plenty of specs, drawings and loadings on them over my time going into detail on it - it was the standard for decades before swivels came about. The roofing structure has been assessed to hold this load based on this design, that is the only trapeze mounted to a purlin that was bent, literally said that in the video.
Great video Mike! Do this kinda stuff day in and day out, So many different ways of doing things and everyones go their own way of doing things! Where'd you get that Unlit level from though aye? 🤔🤔
I know you use a bandsaw to cut the strut just got a Milwaukee metal circular cuts though it like butter leaves a great factory edge. We also hang a m10 rod off the ceiling and use it to stick the laser to for setting the strut Hights. Great video keep them coming 👊🏻
For the Dewalt camp, who want to keep with them, who I started with for a few years before jumping on to Milwaukee, also has a great metal cold cut saw (DCS373NT-XJ) It has a 43mm depth of cut, which is perfect for Unistrut as well as cutting off the excess rod before chamfering with the 3 blade chamfer tool in the drill
saw you do that paint trick in an old video years back, gamechanger. have you done any kind of training course on the cdm regulations? i'm looking for one. cheers
Dude, where's your video of you doing a set on some galv trunking? I've got to do it on a job and was hoping to watch your video to refresh the memory 😅 I'm sure you did it in your old unit
It's not common to use lock washers but depends on the specification. In some factories nilock nuts are used but again it depends on the job specification.
Not necessarily, depends on a lot of variables but in this case the due diligence had been done. Loading is fine but we was advised to not drill any purlins.
Mate, nice installation. I do these big cables on a daily basis in Germany. Please look into the Erico Caddy Rodlock System. What a nice invention. I bet that you are even faster with these.
why don't you get some non spray galv paint '? and just dip it, spraying the cap or a board seems wasteful and your still breathing the aerosolised paint.
Nice Mike , we have just finished the containment to the workshop and server room of a tech company . Trunking , basket and tray hung from the ceiling on trapezes . Be wary of the large cables pushing the trapezes when you bend them and tie them in .

Who exactly is we? You personally?
Also could use spring washers
Edit: just seen that you wrote that
Agree, it's consider structurally sound 2-5 threads.

Thanks Harry, really appreciate it - who knows maybe one day we will 👊🏼
For sloped ceilings we like to use hinged ceiling brackets from Legrand VAN GEEL. No need for bending rods!
swivel mounts for stud
Nice! Swivels are good too, just got to check the loading 👍🏼
@@residualelectrical Yes to be fair the times I've mainly used swivels has been holding up pretty small-size containment, generally for lighting and the cabling for it.
This method went above everybody's head
😂

good vid, always square washer the bottom in my eyes and nyloc nuts, might be over cooking but adds that little bit more

4x185mm 4.2kg per mtr😊 great videos as always 👌

I’m not sure, just the way we do things, I’m not sure how the loading would work with a center support, I’m sure the tray would bow also
I assume this refers to brackets like the 'Legrand OH150PG Overhead Hanger'.
They are available and sometimes used in Britain but not supper commen. Partly due to cost and partly due to the British mentality of not valuing comfort over skills and tradition..
"Don't fix it if it isn't broken. We've always done it like that" 👍
m12 compact band saw, such a beautiful machine.
Class video mate can’t thank you enough for the tips over the years
Thanks for sharing. Really enjoyed this video. I haven’t done industrial for over 20 years so good to see.
Glad you enjoyed it!

For areas affected by vibration I would always use spring washers. Good tutorial though. Miss doing containment.
Great video Mike! Do this kinda stuff day in and day out, So many different ways of doing things and everyones go their own way of doing things! Where'd you get that Unlit level from though aye? 🤔🤔
That’s a handy little level. Nice work and content.
Thanks, it’s a prototype from unilite but will be coming out soon I’m sure 🤝🏼
rather than measuring from drop rod to laser put a centre mark on the bottom unistrut,line to laser and the rods will be correctly spaced
I like lipped washers in place of square washers. No need to square them up and hold them in place by hand while you're tightening.
Thanks, nice video. Can you share measurements of the unistrut cut length, how much larger than the width of the tray/ladder?
I know you use a bandsaw to cut the strut just got a Milwaukee metal circular cuts though it like butter leaves a great factory edge.
We also hang a m10 rod off the ceiling and use it to stick the laser to for setting the strut Hights. Great video keep them coming 👊🏻
I’ve heard a lot of good things about the metal saw to be fair! And yeah great shout on the laser 👍🏼

Excellent presentation 👍.
Thanks!
Need a video on setting ladders and cable tray
Excellent 👌
saw you do that paint trick in an old video years back, gamechanger. have you done any kind of training course on the cdm regulations? i'm looking for one. cheers
Haha long time viewer! I’ve done SSSTS which was quite good, you can also do SMSTS or the level 4 CDM qual 👍🏼
What about using locktite this is what comes to my mind?
Good stuff Mike!
Thanks Jim!
How does one get better at this. Dam I struggle with it for some reason
Dude, where's your video of you doing a set on some galv trunking? I've got to do it on a job and was hoping to watch your video to refresh the memory 😅
I'm sure you did it in your old unit
Are lock washers needed in addition to the standard washers?
It's not common to use lock washers but depends on the specification. In some factories nilock nuts are used but again it depends on the job specification.
does the additional half tonne loading hanging from the roof structure require a structural engineer to assess the design ?
Not necessarily, depends on a lot of variables but in this case the due diligence had been done.
Loading is fine but we was advised to not drill any purlins.
What a ball ache that uni is not being slotted, drilling every bit of uni
Put your window brackets on the strut then offer it up slide window bracket loads easier than lining the holes up in the air
Yeah for sure, due to the lip on the purlins that technique involved removing the bolts, but normally that’s the way 👍🏼
Mate, nice installation. I do these big cables on a daily basis in Germany. Please look into the Erico Caddy Rodlock System. What a nice invention. I bet that you are even faster with these.
Thanks Max! I’ll checkout the Erico bits, nice one 👊🏼
Top work……
Get yourself a Milwaukee Insider and cut your time spinning on nuts to your all thread by a bunch!
why don't you get some non spray galv paint '? and just dip it, spraying the cap or a board seems wasteful and your still breathing the aerosolised paint.
That works great too, both applications have their benefits - this was an old can of spray I’ve had for a while so made sense to use it up 👍🏼
@@residualelectrical at least you don't accidentally kick it over with the spray can method.
Nice Mike , we have just finished the containment to the workshop and server room of a tech company . Trunking , basket and tray hung from the ceiling on trapezes . Be wary of the large cables pushing the trapezes when you bend them and tie them in .
True! It’s also great for getting into places a brush can’t!
Nice job! We got the cables in on Friday actually, had to brace a few bits here and there to make sure the 185’s didn’t destroy the place haha!
💪💪
G clamps are upside down mate
G-clamps can be used in any organisation to fit the profile that they attach to.
Mic one dought u own eletrical work or any company eletrican for u what
I have no idea what your talking about - sorry
flat 45 one hole, one hole or one hole 2 hole to level off the angled unistrut
The galvanizing paint doesn't only come in spray form 😉
Haha I know, paint is good too! This was can of spray was lying around so thought we would use it up 👍🏼
Here comes that whiney (be a plumber they said) voice " you should of used swivel brackets"
Haha they are good, loading on them is 1/4 of what a bent rod can take though!
