The EXxtreme safe is just like the regular 12 gauge safe except they skeletonize the door and then weld a 10 gauge plate on top to strengthen it and cover the front and side gaps to resist prying. When out of stock, you can substitute a model LD2042 or LD2042EX. With the 2042 you leave the pocket between the 12V port and the Multi Media port.
