Cable clips.....

You can get from most electrical wholesalers, and perhaps B&Q plastic wall plugs for the cable clip nails.......

There's a knack to it, but if you haven't got the knack then you can cheat by using plugs made for clips or by using smallish screws or nails and yellow or red plugs instead.

If they bend much without snapping, they aren't very hardened. Remember to use eye protection (if they are hardened).

I tend to tap them gently lots of times, rather than trying to get them in in a couple of blows.

Thanks,

Got a large B&Q in town will take a look in the morning...........

Indeed I tried both methods, in both cases as you got about 4-5 mm into the wall, the sound changed and the things would just bend! Most annoying

Well done Sir - I had no idea that they did that comprehensive range

A tip someone once gave me was to nail them directly below a vertical course of mortar (rather than directly under a brick if you understand my meaning) - on the basis that the mortar has not been subject to weight as it set.

No chance that you are nailing into a steel lintel under the screed, I suppose? That would do this every time. There must be some sort of material change for this to happen at a consistent depth - I'd do an investigatory drill to find out.

Yes. I find a heavy hammer - a club one - used in this way the most likely to succeed. Although it still requires a deal of skill if the material is hard. Using the special wallplugs makes life easy - if it's easy to drill at the location. But they're not that readily available - TLC etc don't seem to stock them anymore. I've often meant to look for a cable tie with screw fixing at a reasonable cost - this could have many such uses.

If you find one, do let us know...I really need sometuing like that.

Thanks guys,

Took a stroll around B&Q today, and in the electrical section along with the cable clips, they had the tower pin plugs. Job done. In answer to the above, there was nothing behind, just rock hard cement I guess, but drill went in ok.

Nice to know. Now all I need is an SDS bit in that size. ;-)

Yep. A far neater and quicker solution if you can't get clips in is to use some mini-trunking and drill, plug, screw every 18" or so.

When I was installing electronic time systems the flat-packed stuff which came rolled up in a box was used everywhere. R-S used to do it.

Just pull as much as you need out the box, cut to length (channel + lid rolled up as one) fold up, fix and clip the lid on.

The open ends of the trunk can be closed over by cutting the lid longer than the trunk, removing the "track" with a stanley knife and folding it over before clipping.

Both internal and external angles can be made in the same way so corners can also be made neatly.

Plus it keeps the elements off the cable (not that that's really a problem)

Just another idea as I have experienced walls many times where the brick is too hard and the mortar either too brittle or too soft for normal clips.

Found them in my local B&Q - thanks. But no indication of drill size needed on the box or plugs. They are just under 5mm in diameter but I'd guess need an interference fit. I was also surprised to find a 4mm SDS drill on sale - didn't think they did them that small. Perhaps it would be ideal?

Screwfix do them here:
