The boxes are constructed of solid stainless steel and are secured by dual key locking mechanism. One key, known as a proprietary key is held by Interbrinks Shipping & Security Company Limited (IBSSCL). The second key, which is unique, is kept in your possession. Both keys must be inserted simultaneously to open the private deposit box. Within each private deposit box there is a self-contained metal ‘bond box’ that allows easy access to your possessions. The box may also be padlocked by you. Our private deposit boxes are available in 4 sizes. IBSSCL offers access 5 days a week, between the hours 9.00am and 3.30pm. Access can be arranged out of hours and in weekends. (conditions apply). Access is by appointment only.
