bought this to keep my trailers from being stolen, anyone with a hacksaw and 5 mins can cut this and be on your way, anyone with a cordless saw can cut this through in less than 30 seconds and hit the road. It is made of thin steel and can be torn apart easily. Don't waste your money on this garbage. The good news is that it gave me the idea to design and develop my own heavy steel project that will last a lifetime.
