I bought the Bulldog EM4X4SS wheel clamp for a motor home, i couldn't decide what means of security to use until I saw the bulldog EM4X4SS, its very visual with its bright yellow decals and soft yellow edges to prevent alloy wheels from being scratched and is very easy to install, fit both halves around the wheel slide together and push the lock "click and it's fitted. I can fit the Bulldog Em4x4ss in under 10 seconds and feels very secure when fitted, as soon as you pick up the Bolldog EM4X4SS you can tell it is solid and well made.I wish I had bought a Bulldog EM4X4SS when I had a caravan instead I struggled with a useless Alko lock, do yourself a favour and get a Bulldog EM4X4SS, you don't even have to line anything up. Five star quality and security.

Substantial clamp but fear that the lock is a weak point, especially to a determined thief. Is it any better than a crooklock? it's the same type of lock. PS I think you ought to state in your advert that it is sealed with a lock, but that it is not necessary to use a key to put it on.

It appears strong enough to deter a thief. The first time it got wet the plating discoloured and the lock became stiff

I brought the Bulldog EM4x4SS Euro Clamp to use on my works van as one i had in the past that wasn't up to scratch, this Bulldog 4x4 clamp one was better as fitted onto the rim knowing it was meant for a bigger wheel, when you're not using it, it being small and almost compact it fits nicely away under the seat or space in the van so not in the way for passengers or load within the van, The euro clamp is easy to fit and doesn't take long to put on or off the vans wheel, its a great deterrent as a visual wheel clamp to so it noticeable when thieves approach if they had thoughts on stealing the van, i would recommend to a friend or work mate to get one and use it on there van/4x4

robust/good lock/heavy when in one unit, a little awkward to fit onto wheel first time use
