Portable surge protector

I've used a Progressive portable surge protector for many years. I've never had it stolen. I RV alot...mostly in the West, but I have been across the country and into Canada. More times than not, I don't lock it to the pedestal. But when I do, I use a length of loose chain link with padlock (or bicycle chain/lock). Thread the chain through the bracket that comes with the unit and anywhere around the pedestal that seems secure. Sometimes I find something sticking out from pedestal to put it through, sometimes I just wrap it tight around the pedestal and hope it's secure.
