Barrel lock for storage container i.e. Yellow Box /Shurguard (Epping CM16)

This barrel lock is the kind that you have to buy from a storage company when you rent out a unit. They don't take them back when you give up the unit. This could be useful to someone who is thinking of renting a unit from one of the big companies as they charge about £20 for them. I can leave this outside once I know someone is coming to collect it.
