Special Features:

This is ISM's top of the line maximum security safe. The Super Diamond was created as a result of ISM's conviction that a safe of such a high security rating could be produced at a reasonable cost, and thus meet security needs for extreme risk protection. 


The overall thickness of the door is 10 inches. It is constructed of 6 inch thick layer of protective materials. This includes a 4.5 inch thick layer of Alchronite, ISM's patented torch & drill resistant composite material, as well as thick copper bars placed around the frame on all sides.  


The body of the Super Diamond is cast in one piece for extra strength and protection. The casting is Alchronite of 3.4" thickness that goes up to a maximum thickness of 7.1" at the boltwork protective area. In addition the body is constructed with a dense layer of Insutex, ISM's superior insulation material to protect the safe's contents against severe fires. Around the door frame area there are copper bars on all sides for added protection against torch attacks. 


The ISM Super Diamond comes equipped with U.L. listed Group 1 manipulation proof combination lock. A second nine lever double bit key lock is provided in conjunction with the combination lock. As an option, all models accept a three-movement time lock. 


The bolt work and locking mechanisms are of extremely high strength construction in order to ensure that they withstand explosive, torch and sophisticated tool attacks such as with drills. Massive steel blocks encase the bolts which slide out in three directions with fixed bolts on the hinge side of the door. 

Relocking Devices:

The area of the locks and the vital mechanism areas are protected from attack by a special glass plate, which if tampered with, will release a number of randomly located re-lockers independent of the locks. This is ISM's system of not only providing protection but also deterrence. 


Interior Fitting:

Adjustable / removable shelves are available for setting up the safe interior to accept trays for jewelry, cash, and other valuables. The Super Diamond has an inner vault activated by a key lock.
