How to fix cables to walls

How to fix cables to walls


in this video I’m going to take a look
at how to clip cables to walls this is particularly useful if you are
installing CCTV etc. before we start I’d like to point out that if you are using
masonry nails you should wear a good pair of safety glasses the first thing
you need to do is get the correct sized clip for the cable that you are using
basically there are two types of cable there’s round cable like that or like
that which is cat 5e cable or if you’re installing a fixed electrical
installation you get twin core and they’re careful wire which is often
called flat cable so for a flat cable like that, you’d use the correct clip like so
that will then hold the cable in position if you are installing twin
core and earth cable like that, there will be a guide inside of the on-site guide for
the latest electrical regulations which will tell you approximately how far
apart you need to space the clips it is important to get the correct sized
clip and for this earth wire that is a seven millimeter round clip you can see
that that is the perfect size for that well you don’t want to do is get one
that’s too big that’s a loose fit on there and you don’t want one that’s too
small so for the majority of cable clips these all come with a masonry nail
installed like so now the problem with masonry nails is that you can’t actually
knock them into brick or hard concrete you have absolutely no chance so what
you tend to do with these is knock the mass of a nail into the mortar between
the bricks the problem with that is that sometimes the mortar is so tough that you
can get them in and also some mortar especially on all the properties is very
crumbly you’ll knock that in and it just won’t hold at all for larger diameter
cables you can get cable cleats these are also very handy when a few small
cables need fixing close to each other if you have a property that which
is rendered or pebble dashed on the outside this can make it extremely
difficult installing cable clips it is important when you install an external
cable that you have a drip loop and it’s important to always feed the cable in
from the bottom what you don’t want to do is put an enclosure on the wall or
anything like and up the cable going in the top because that is where the water
will get in these are a great idea these are pro fix nail plugs what you do
with these is you drill a 5 millimeter hole knock that into the wall and then you
can actually put the masonry nail directly into that and that will hold
really well the advantage of these is that you can use these on virtually any
wall so if it has been rendered or pebble dashed or if you need to fix into
the brick you can do so using these very easily cable cleats are used for armored
cable and you would normally use a standard plug and an external screw to
fix the cable to the wall but these are also very handy if you need to fix a few
smaller diameter cables such as network cables or camera cables to the wall so
recently I did a job and actually just used a cable cleat like so and I’ve
drilled two holes put two wall plugs in and used to external screws and that
held the cables perfectly you could even probably get two or three more cables in
there so if you get the clip put it on the cable put that in position where
you want it you don’t actually need to hold the clip you can just let it sit on
the actual cable and then you can just tap that in gently using a hammer you do
need to use quite firm blows and as you can see that has now got that
you could then put you next clip in a bit further down the spacing will depend
on which cable you are using and how flexible it is so basically if you are going
horizontally you can follow the horizontal mortar lines or you can
follow the perpendicular ones if you are going down vertically the pro-fix nail
plugs are a great idea but unfortunately some cable clips come with very small
masonry nails just take a look at this which is CAT5 cable you’ll see that
that clip is the correct size but look how short the masonry nail is that
it’s not much use use at all. we’ve then got a white one and that is the correct clip
also for that cable but look at the difference in length between the nail
there is a massive difference between the two it’s probably two or three times
longer so if you are using the Profix nail plugs you are going to need the
larger masonry nails and you may find that when you remove the small masonry nails from there, that the larger one won’t actually go through without splitting it
so if that’s the case you can simply take a small drill bit and that is a two
millimeter one and you can actually do this just by hand, you don’t need the
drill you can just twist that through there and that will enlarge the hole
sufficiently for a larger masonry nail you can of course get different colored
clips you can normally get gray ones black ones or white ones if you do need
to use the nail plugs you can simply drill a five millimeter hole tap the plugin you can then take the cable, push the clip onto it and you can simply align that up and just tap the masonry nail into the plug and that will give you a very good fixing so if
you are buying cable clips it’s often a good idea to go in the shop and then you
can see exactly which ones you are buying obviously the ones with the
really small masonry nails are not much good at all. In this example I’m
installing three CCTV cameras on the side of this house you will notice that
I have fed all three cables through a disused overflow pipe which was
redundant from when a new boiler was installed all three cables run down and
then have been fixed at a while using cable cleats, wall plugs and external
screws then the cables have been clipped to the mortar course using the correct
sized cable clips the overflow hole has been sealed with clear sealant to
prevent water ingress when fixing cables to an external wall at height, it is critical
that someone foots the ladder for you I do know someone that died falling from a
ladder so do not take any risks sometimes it’s possible to do vertical
runs by fixing the cable to a down pipe accessible using cable ties I hope this
video has given you a few tips for when you are installing cables if you found

  1. The nail plugs are new to me and i buy them tuesday immediatly.
    Thanks you for sharing and caring! Happy Easter sir!

  2. Not seen those nail plugs before, very nifty on rendered walls… Cheers for the great tip, I'll be getting a few of those for my Cat-5 network cables ๐Ÿ™‚

  3. I do all the cable routing internally and exit the cable as close as possible, preferably right behind the unit to be hanged outside. It prevents the cable rotting away and is easier to replace in bad weather should it break, which is unlikely. External CCTV cables leave them vulnerable to physical interference.

    It's extremely important to use only black sheathed cable externally as it is more UV resistant than any other colour.

    Feeding cable through mortar needs to be sealed with a plastic cap and sealant. Preferably the cable should go through brick and sealed with a plastic cap or the back of the unit you're fitting. Nail cleats should be a temporary fitting unless you use them in wood. The screws and strap is the best way externally as it won't pull from the wall in a strong wind.

  4. Thanks for the video – the clip plugs are a good idea – never used them before. What is your view on running normal twin and earth outside, say to an external light. I've seen somewhere that this should be avoided as the cable "ages" in the sunlight?

  5. i known someone who used to actually lay the cable in the brick joints and repoint over it …………. yh, maybe pass regs if its just a data cable but hell no for electric

  6. I was just looking for this last night. Planning on running some cat 6 and I have rendered walls. This has been so helpful

  7. Hello what do you suggest to use if you've got external wall cladding , I cant see the brick work at all . The cladding is 100ml with a rendered pebbledash surface.

  8. Yes I did this job a few weeks ago fitting a camera and two smart colour changing LED lights on our back wall. Lost a few clips which will no doubt show up in my motoryclce tyre in the near future. I also fitted a hidden internal switch (well it's behind the curtains) which works well and nobody died (yet) so all is well. Happy Easter mate

  9. Another great video, always wondered what was the best way to fix cables, now I know, something you can't learn from a book, the nail plugs look good…thanks

  10. Damn those nail plugs. I've always knocked in a cut off piece of hardwood dowel and a squirt of 'no more nails'.. It looks like I'll be heading off to eBay now! Thanks Chez.. ๐Ÿ‘
    Edit; that's that done. ยฃ4 for 100 pieces..

  11. Great tip, Mr Ultimate Handyman. This has come at the right time for me. We have an older house and the bricks/mortar are like granite. Thanks for the video and have a nice Easter. Now's the time to plug in that beer fridge into that outside socket that you previously fitted. Cheers.

  12. Just been cutting the grass and the lawnmower has stopped working Iโ€™ve changed the fuse on it but nothing any suggestions itโ€™s a flymo electric lawnmower

  13. Nail plugs! TBH I have never heard of them but what a brilliant idea…Cable clip nails hardly ever go in successfully!!

  14. Excellent timing this Chez.. Just had our roof redone..and now need to resecure the aierial cable..:) Bikini weather in Darwen today ๐Ÿ™‚

  15. I'm the same about nail plugs,I'll have to invest in a box of them. Didn't know they existed๐Ÿ‘๐Ÿ‘๐Ÿ‘๐Ÿ‘๐Ÿ‘. Some of us are working (treble time ๐Ÿ˜ฌ๐Ÿ˜ฌ). Enjoy the holidays everyone. Ps how's the ticker doing.

  16. Good tips for surface cabling. I always try to put cabling in external cavities where possible, especially security and cctv cabling.โœŒ๐Ÿ˜Ž

  17. Nicely explained yet again. You are a multi-skilled guy, UH. I've never seen these nail plugs – thanks for the heads-up!

  18. great vid didn't know the nail plugs existed. what size/length of nail would you recommend for the nail plugs. Many thanks

  19. the only thing you have to watch with internal cable clips is they have to be metal or fire resistant around internal door ways even when inside trunking

  20. Great, after Iโ€™ve just pegged 30 metres of cable around my garage and car port fir new security lights you come up with a solution to cable clips not always fixing…..ggrrrrrrr. ๐Ÿคฃ

  21. Damn,now you tell me nail plugs exist! Two months late๐Ÿ˜ญ๐Ÿ˜ญ๐Ÿ˜ญ๐Ÿ˜ญ๐Ÿ˜ญ๐Ÿ˜ญ๐Ÿ‘๐Ÿ‘๐Ÿ‘๐Ÿ‘๐Ÿ‘๐Ÿ‘๐Ÿ‘๐Ÿ˜ฏ๐Ÿ˜๐Ÿ˜๐Ÿ˜๐Ÿ˜๐Ÿ˜

  22. Great tips as always! Nail plugs! Fantastic what a great idea. I have used cable tie plugs before. You drill a 6mm home smack the plug in which has a cable tie loop and then fix you cable over it with a cable tie.

  23. Most cable and sat TV installers go on a special course where they teach them to drill a cable hole from inside the house with an SDS drill and push it as hard as they can so the hole on the outside busts the brick face and is at least 10 times bigger than the drill bit…..nice tidy work as usual UH ๐Ÿ™‚

  24. You give great advice. I find a lot of what i need on the tube. A lot of it is from the US. I have a major thing that needs to be done. Power to my garage to make it a work shop

  25. I cut the end off an SDS chisel (from one of the Screwfix combo sets) and drilled a small divot into the end with a 6mm drill. Put your SDS drill into hammer only, and it will drive wall plugs in like butter.
    Also, if you put a short piece of 20mm HDPE around it to act as a sleeve, it makes a good earth rod driver.

  26. how would you go about fixing to rendered or pebble dash wall? wall plugs and screws?

    would the same apply to running cables in conduit/pvc pipe?

  27. one thing to add to this if you are installing it cables inside the property you now need to use fireproof clips if there is any chance of the cable collapsing prematurely. That applies to telecom data CCTV as well as mains

  28. Nice advice there. I favour knock ins. You can secure multiple cables easily and add more at a later date if you wish.

  29. Cables clips/ cleats need fire rating now mate dont forget 18th edition requires all areas not just fire exits now. Keep up the good vids

  30. Wow, I never knew you could get special plugs to nail clips into – I used to just remove the nails and put screws in and just use bog standard wall plugs. Also, I like your life hack with the SWA cleats – I doubt any sparkies do this but it's a neat little idea. Good video ๐Ÿ‘

  31. Great tips there, thanks. Must look at nail plugs next time, had too many frustrating cases of trying to knock masonry nails into perished mortar.

  32. We used to use those nail plugs but noticed that they were often twice the price of an equivalent Tower wall plug. Nail plugs are around ยฃ2.60 per 100 and the Tower plugs are on average ยฃ1.20 per 100. We use the Tower plugs on all our cable jobs now and they work just fine.

  33. Been using rawl pugs as nail plugs in some situations for years ,I thought most tradesmen did .Never use a screw where a nail will do !

  34. I have found one can pull the nail from the clip and then drive a suitably gauaged screw through the hole. A hole can then be drilled and plugged and the clip screwed in.

  35. Excellent video, thanks. Don't know how I missed it when it was first released. Learning points for me were the nail plugs, the opened saddle for several cables and drilling to open up the hole in the clip for the larger nail. All brilliant, thanks.

  36. ordered nail plugs – we dont have them in Israel, never knew they even exist. i will try to use wood chips till they arrive. Great video, thank you!

  37. You could drill into the wall and use wooden dowels and tap the nail into the dowels, Just a cheaper idea.?…thanks for the video

  38. There has to be some real good cable clips with masonry nails rather than having to switch them. ive gone through so many and you get some concrete which will bend any nail. i dont really like the idea of wall plugging before fixing for a cable due to the time overhead on long runs
