The Mutual Cat 3 drop safe meets the SABS (Cat 3) requirements against various forms of burglary attack. Firstly the sophisticated methods of lock picking or pin point drilling are negated by the use of high security locks. Additional protection is offered against forceful attack methods using cold chisels, drilling machines, various hand tools as well as high speed angle grinders. The deposit drawer also has adequate protection against similar forms of attack. Furthermore, protection against the illegal removal of deposits through the drawer is provided through a system of baffle & anti-fish plates.

The Mutual Cat 3 drop safe has a 60mm solid high tensile steel door and an 70mm steel body. 3 solid plated locking bolts secure the door upon locking and sturdy ball-bearing exterior hinges ensure ease of opening. It is fitted with 2 high security key locks and an additional one on the drawer. Highly recommended by the South African insurance industry, the category 3 model provides an SA Insurance Association overnight cash rating of R100,000.
