Ok, they are not exactly the same in the fact the they are not made by pure freedom, BUT they are exactly the same setup, the cages are made by an engineering firm just like pure freedoms are, I've seen a pure freedom cage and it looks Identicke to the cleaning warehouse.
At the end if the day no tank frame has been crash tested apart from ionics.
apart from alex and ionic,
Pure freedom are owned by adepter engineering, they are the engineers they are built in house.
it is easy to copy a box, is the weld the same I can't answer that as never seen one, I have owned a purefreedom one so I know they are quality.
Ionics crash test IMO is worthless due to the speed it was tested at, I drive at least twice the speed so renders it untested at normal motorway driving speeds, but thats another convo
