SA5 is a combination lock safety system developed by Roman-Jones. It is designed to keep valuables such as firearms, ammunition, money, and jewelry secure and provide reliable protection to its owner. SA5 lock systems offer high security with a unique key code technology that requires an individual combination code of five to eight-digits to open the system. The combination code is only known by the user and can be easily reset or changed at any time if needed. SA5 lock systems are also equipped with anti-drill protection that makes it difficult for burglars or intruders to penetrate the system. Furthermore, SA5 lock system components are made from high-grade hardened steel, and they can be easily integrated with other security systems such as alarm systems and cameras.
