I have lots of fencing panels supported by concrete posts.I want to run training wire along the fence but am worried that I will damage the posts if I drill into them. I know they have reinforcing steel rods inside and have heard they are brittle and may crack. I have seen a very expensive clamp product - over £3 from Riverglen. Anyone got any better ideas?

    I'd have thought they would have been sturdy enough to take a small hole drilled in them Gold1locks, but maybe you'd be better attaching battens to the ends of the wooden panels instead and running wires through vine eyes fixed to those?

    Hi Fairy the trouble drilling into conyposts is that you will probably need to use the hammer part on the drill ,this is the prob, but i would try a 5mm or 6mm mansony (concrete bit) with the red rawl plugs ,if you cant borrow one their about ??4 for a decent one ,a cheap one will not drill straight thats when they sheer off target and lumps of cony come off, if you have a smaller bit then do a pilot hole first at the base of the post just in case its not going to have it at all,if you do go to builders supply yard or iron mungers they will give you what you need, you dont have to pay the earth,what about borrowing a bit and just get the plugs to fit ,then you can get the eye screws to simply screw in, if it looks like its going to be ok remember to drill dead center,pilot first a little deeper than the plugs Or you can do what my neighbors do and shout "" Alan avyagotaminint """

    good luck Alan

    Never had the concrete posts but I know what you mean...a smaller pilot hole is what I would have tried and then increased the size. I suppose it's like drilling into tiles -same type of issue image

  • We are Rivelin Glen Products who have designed and manufacture the Wire Anchors for concrete posts.  The price quoted is incorrect a pack of six is £15.50 and this includes free delivery.  Very simple to install in a few minutes, so will save you hours of work trying to drill the posts which have been known to spall. We also have a bracket which slots down the back enabling you to buy various size rings and hangers  for pots and hanging baskets. See us at

  • I have used these products, expensive but do the job.  However - be aware that for some older concrete posts you will/may need a Size 1 and a Size 2 per post as the slots on each side are not the same so always measure both slots in each post. In the past I've tried to force a Size 1 - it won't work.

    £2.50 or £3.00 per anchor, it still ain't a cheap option if you have a long run to do! imagePS, I've just had a look at the website and they are £15.90 not £15.50 for 6.

    If you're going to chastise others for getting the price wrong you need to be a little more careful.imageimage

  • We try to keep our prices as low as possible and all our prices have free delivery.  Unfortunately the price of steel and manufacturing has gone up. Once the brackets have been fitted they will last for years. We also sell the trellising system - GRIPPLE which makes the job quick and easy to complete without any sore fingers. Our add on fitments make it possible to attach pots, hanging baskets and bird feeders on them.

    Apologies. I hadn't realised how old the post was.
