Both my existing cabinets are brattensound so I’ll give a direct comparison when the ultimate safe arrives in a few days - to me the folds are not going to make much difference as the fastest way into a cabinet is to go to any Aldi and buy a cordless angle grinder! Not the most quiet method but neither is Jimmy if open a cabinet with a crow bar.
and by ticking the box it should also protect the guns as let’s face it - the cabinet is a last line of defence…if they got to the cabinet you have bigger problems as they are in your house.
