The dormakaba Cobalt security lock is available in both single and double action configurations, making it suitable for a wide range of applications. The single action version is ideal for doors that require quick and easy egress, such as emergency exits. The double action version is designed for doors that need to be secure but also allow for easy access in both directions, such as swing doors. Both versions feature the same high-security locking mechanism, with a patented design that resists picking, drilling, and other forms of forced entry. The Cobalt lock is an excellent choice for facilities looking for a versatile, durable, and highly secure locking solution.
