MagnaMole Magnetic Cable Guide – As Seen On Dragons Den

For Sharon Wright from Scunthorpe, she really did have a eureka moment with her ingenious magnetic cable device called the Magna Mole and the dragons from BBC’s Dragons Den loved it too.

Sharon came up with the idea of the MagnaMole, after having an installation done by BT and the engineer using a coat hanger as his only tool to guide the cables through the cavity walls on her new home.  Not only is it dangerous, it’s also very time consuming to try and wiggle the cables through and this is where Sharon had her lightbulb moment.

UPDATE: We’ve spotted the MagnaMole available to buy on eBay from around £6 making it a bargain and the perfect tool for any electrician or handyman. Buy yours today.

Push the rod through the wall. Screw the magnetic cap to the cable or wire, attach to the rod and push it through the hole from the other side…. MagnaMole is as simple as that!

Put simply, Magnamole is a magnetic cable guide that draws cables through voids. As the name suggests, it is all about magnets. The magnet on the rod connects with the magnetic twist end, which you put on the cable. There are different size magnets twists to suit different round flexible cable sizes. Really, this is a tool for communications, alarms and low voltage cables rather than heavier power cable. The magnet is powerful, but if you try and pull cables through the chances are that you will lose contact, so push the cable rather than dragging it.

The high visibility paddle on the end will protrude out of the hole as you push the cable through, and it has been designed so it won’t cause injury. This is a real advantage over the bent wire coat hanger. Of course, a bent wire coat hanger will always have its place in the electrician’s tool bag but the Magnamole is another tool in the armoury

Cavity wall insulation is another consideration when you are poking cable through and the straight through contact helps to keep the hole open. Once the drill is through you can put the Magnamole on the drill end and bring it back, and then put the cable on the device and go back the way you drilled in – that way the hole stays open.

Included in the MagnaMole kit is a 10mm masonry bit, 400mm long. It is rotary rather than SDS so you can avoid breakout. You also get the Magnamole and three twist ends as part of the set.  BT have already placed several orders for the MagnaMole for their staff to use and that’s testament enough to buy one and was enough for Dragon’s James Caan and Duncan Bannatyne to invest £80,000 into Sharon’s company – Talpa Products.

Now available to buy from Amazon.co.uk and the Magnamole has been literally flying off the shelves since it was featured on this week’s Dragons Den. Buy your MagnaMole online here from Amazon.

    Personally I can’t see what the fuss is about this product. I am an electrician and I have never found my self looking around for a coat hanger to pull cables through a wall! Cable rods have been around for years, flexible fibre rods which attach together and draw cables through a desired route. This product is just a twist on a theme, nothing special.

    I think this product is absolutely superb. My brother is a B.T. installation expert and he says it is the best product in his tool bag. He says that the product comes into it’s own when there is an offset in the holes or when you need to go round corners. Flexible fibre rods are absolutely no good in this situation. I think it is one up to the girls and I think the previous comment is just sour grapes. Excellant product and exceptional performance on Dragon’s Den. Well done Ms Wright

    I have been installing cables in the communications industry for 10 years and use the coat hanger at many installations. We drill from the inside to the out, then push the coat hanger through wall, then we go outside and push the cable onto the coat hanger and finally push the cable back through the wall with the coat hanger acting as the guide for the cable. There’s no wiggling around because If the drill bit went through the holes so will the coat hanger, as for going round corners, forget it, it’s highly unlikely to work because the rod will be bent and jammed against the wall like a spring and there’s no way you could push that through with cat5 or 3 pair telco because it will bunch up. Truth is, not one system is perfect, both the coat hanger and Magnamole will struggle when there is debris such as insulation in the cavity because of friction on the guides. In that instance, I drill the hole, then push a 24″ piece of 3/8 brass tubing through and push the cable through the tubing it beats both the coat hanger and Magnamole. So my hat it off to Ms Wright for making us believe this is a revolutionary idea and selling it to us when in fact she saw a BT guy doing the same thing with a coat hanger and claimed it as her own idea. Which, is suppose, is the definition of an entrepreneur. :-)

    I have just shown this article to my electrician who is currently pusing cables through my walls using a hook. He had never heard of this but will be getting one now. He said he had often thought there ought to be something better than a wire and a hook.
