the wall on the locking nut device is completely different to the ones fitted by ford, and they have many differnt patterns. the device itself is absolutly secure due to the thickness of the metal which surronds the hub of the caravan, and due to any person trying to burn, saw, grind this off they will have a waste of time trying ot remove it.
anybody who has a caravan stolen or anybody who is wanting to purchuse a secure device, instead of a cheap whell clamp( which they may be covered by insurance but dont work) should invest in one of these. they are worth every penny.
if however you want more proof or info just ring the number on the hublock web site ( www.jsbhublock.co.uk) as he has all the info needed included all the things that they tried to use to get it off ( and failed)
this is the best thing we have bought for our caravan, and we are really please with this product as we are now safe in our minds that our caravan will not be stolen from us again
we are just wanting to let people know of this product so they dont go through what we went through ( after all we didnt think it would happen to us, that this kind of thing only happened to other poeple but it did), and we wouldnt buy it, if it didnt work once in a lifetime is enough for us
