"PR4 - DIMENSIONS H x W x D(mm) 1075 x 660 x 660\r\n\r\nThe design of the safes and materials used provide defence barriers resisting to:\r\n\r\n \tOxy-Acetylene attack\r\n \tDrills and abrasive grinders\r\n \tExplosives and force\r\n \tPneumatic and hydraulic tools\r\n\r\nBODY: The body gives a minimum thickness of 80mm of high density refractory materials at all points. These materials are bonded between inner and outer walls of specially reinforced steel, becoming a complete monolith after pouring. The engagement of the door and body effectively result in a continuous cube of exceptional strength and security.\r\n\r\nDOOR: The door of the Premier safe has an overall thickness of 135mm, and the 55mm thick defensive slab section contains metals highly resistant to drills and abrasive grinders in addition to the high-strength poured barrier materials and other defences. The lockcase forms an integral part of the entire door structure, giving additional strength.\r\n\r\nBOLTWORK: Heavy 32mm bolts provide 4 way locking into reinforced sections of the 2 sides, top and bottom of the safe body\r\n\r\nINSURANCE COVER: Insurance surveyors have suggested $100,000 as a realistic rating of overnight holding of cash and valuables in an unsupported situation.\r\n\r\nOPTIONAL: 115mm high lockable roll-out drawer can be provided to secure in the bottom of Premier safes at additional price.\r\n\r\nANCHORING: 2 x 20mm recessed holes are provided in all models for anchor mounting to floor.\r\n\r\nLOCKING: One La-Gard 6 digit electronic combination lock which secures the heavy duty 4 way locking 32mm bolt work, further supported by two automatic glass relockers.

A high quality key lock can be fitted as an optional extra if required at an additional cost.\r\n\r\nFINISH: CMI Premier safes are available in attractive enamel hammertone durable finishes to suit any office decor.
