"Made of 12 gauge steel". To be clear, this vault is not actually a vault, it's a lid, which is conveniently not mentioned anywhere in the advertising. So while the lid may be made of 12 gauge steel, the other five sides of the vault are plastic, the plastic that comprises the center console. Hardly a vault, and hardly worth the premium price.

As another reviewer had said, this is not a vault it is a lockable steel lid to the space below the tilt up console cover. It utilizes the flip up plastic divider as security from the front, at the bottom of the console. It does however give the illusion of security if you are not a determined thief. My last vault was fully steel and very secure, this is a deterrent only if not knowledgeable on this specific design. I am not the fan I once was.

disappointed that it does not have steel bottom like my previous model. it is open to the floor and rear.

I have to say that I could not be happier. I was amazed at how quickly my new Safe arrived. It did take a little finesse to get the safe to slide in but once it is in it fits perfectly and looks great. I would highly recommend this one for anyone

Very well made vault and super easy installation, fits like a glove!
