For sale is a Size: OD: 74"H x 43"W x 30"D ID: 62"H x 33"W x 19"D Safe is in working order. I will have a locksmith over at 3/28/13 to change the combination. It is a large safe. Class 150 means that heat sensitive media, like magnetic tapes and DVDs, are protected at much lower temperatures. ``It is important to note that certain valuables, such as photographic negatives, analog film, and legacy computer backup media, such as floppy disks and magnetic tape, are particularly sensitive to the ravages of heat and will begin to degrade at temperatures significantly less than 350 degrees Fahrenheit - the litmus test for a fire resistant safe designed to protect documents. To protect these types of valuables, you should store them in a media safe also known as a data safe. This is a special type of fire resistant safe designed to maintain an interior temperature of less than 150 degrees Fahrenheit. Unfortunately, the manufacturing cost per cubic foot of storage space inside a media safe (Class 150) is much higher than that of a document safe (Class 350). For this reason, the price of media safes is generally much higher than that of equal-sized fire resistant safes designed to protect documents.''
