Caravan wheel clamp

I use the Lock below, on boths sides of our Tandem van, carry on the 2 spare wheels at back of van with additional hardware to ensure that they do not come off during travels.

Agree easy to cut thru. Also have a Towball lock and a Tracker, Telstra Sim connected to a Mob Phone Aerial above our TV aerial.

You could cut them with an angle grinder but I there's going to be a lot of noise
and sparks flying and generally crooks don't want to draw attention to themselves.

Surprisingly I did see a video where a guy was trying to remove different kinds of locks and
the first he tried was the a wheel lock and he gave up on it. Couldn't beat it without a grinder.
