Re: Cable clips on stone wall

How do you attach cable clips to a stone wall? =A0If I manage to hit the

ISTR the proper way to lay small cables, that normally have nailed clips, on hard walls, is to first screw a strip of wood to the wall, and nail to that. Or you could fit a length of conduit, you won't need bends or conduit boxes for sheathed cable, just straight lengths to provide support and protection where necessary.

Drill/bash a hole in the wall, hammer in a bit of dowel, then cable clip to the dowel.

[D.M.Chapman]

Yep, drill small hole, push in a pin plug and then use normal cable clip.

I use hammer-in cable tie bases, for example eBay 250694479160. I have the opposite problem of old soft red bricks but the hammer in ones should work on hard stone as well. You might have to experiment to find the best size of drill. Great thing is when you want to change the cable you just cut the cable tie and use a new one around the new cable.

I prefer to use the plastic plugs with tie-wrap slots.

Use an SDS to drill a hole, tap the plug in with a hammer, and tie-wrap the cable to the plug.

Very fast and convenient.

Now here's a thing. If you're caught out with no plugs or anything, if you drill a hole just a few mm deep and then tap the nail into it, often the nail will penetrate further and will fix OK. Bricks must be hardest near the surface.

Also the vertical mortar joints are often softer than the horizontal ones.

Yep, they are, so I was told by a builder.

Also the vertical mortar joints are often softer than the horizontal ones.

Also available from Toolstation, Screwfix, TLC etc. I have Toolstation ones, they need a 9mm hole in sandstone. 9mm SDS drills are not carried in any of the sheds I looked in...

And being all plastic won't rust and fail like nails will. Only use plastic, brass or stainless steel for fixings outside or in places that may get even slightly damp.

but use good quality black cable ties, otherwise UV will make them go brittle and drop apart.

Drill to take a small rawlplug, use a black P-clip just big enough for the cable (eg, 1/8", 3/16", 1/4"), use a small stainless screw (#6). You can pick up the black P-clips & small packs of stainless #6 screws on Ebay.

Fix to the vertical mortar points so the cable runs in the mortar line (P-clip will offset the cable).

This way the cable can be replaced easily without ripping chunks out of the wall with nails. Done carefully it can be very neat - P-clips allow adjustment to avoid festooning (dip-dip-dip).

alexander, simply nail into the black mortar/cement joints (using long masonary nails as necessary) - the cable clip fixings will not be equally spaced, but better that than damage the stone work.

This by the way, is the normal practice for me (and I nail into the cement joints on brickwork too), but others may differ.

Or whatever line you want :-)

My point being the P-clip will offset the cable from the screw line, so if you screw it into a horizontal mortar line the cable may appear to increase the thickness of the mortar line and so make the cable more obvious. It is however better than nail clips which tend to corrode & blow out taking a pyramid of mortar, just fall out, or generally not go in in the first place.

[Frank Erskine]

Possibly because the horizontal mortar is being compressed as it "sets" by the bricks above. The vertical mortat just does its own thing.

More likely the 'economical' way of buttering the perpends. Just a narrow strip on front and rear rather than a full dollop. A few years down the line and a re-point is necessary.

[wrightsaerials]

Normal cable clips have normal steel pins, and I've never known them fail due to rust.
