At STUV, we understand that correctional facilities require the highest levels of security, reliability, and precision. That's why we deliver complete solutions—from mechanical prison locks to modern access control systems—that are always tailored to your needs. Every step of the planning process is transparent, and every lock is designed for flawless performance in demanding environments.
The process begins with you. From the initial consultation, our specialists listen carefully to your needs and then conduct an on-site visit to assess your systems and challenges. Based on this, we prepare a needs analysis, determine the types of locks required, and, if necessary, create a locking hierarchy with clear security levels and access rights.
We will provide you with sample locks for testing within a short period of time. On request, we can also carry out test installations on site with a test phase in daily operation. This allows you to verify the reliability and functionality in advance before making your decision.
