So I found a safe at a local retailer that had been dropped in delivery, and got an excellent deal for buying it damaged. The interior shelves were all laying in the floor of the safe, all the brackets had fallen off, but biggest issue was that the inside door panel that is basically just a piece of sheetrock with felt on the front is broken and out of the door. Issue is that there is a lip at the top and bottom that the panel goes into, so i am unsure how to replace without cutting the door or using multiple pieces to insert. It is a Cannon Safe http://www.cannonsafe.com/tractor2.html So I have 2 questions. 1. is that piece functional as part of the fire resistance or only cosmetic to hide the internal parts of the safe door? 2. has anyone replaced inside door panel on a safe without cutting the door or replacing with multiple pieces?
