Product Overview

Winkhaus N-tra 45G/30 nickel cylinder lock is designed for secure access control in residential and commercial doors, offering certified class 6.2 C protection. Used by builders, locksmiths, and security system integrators, it comes with 3 patent-protected horizontal dimple keys and meets stringent security demands for doors requiring high protection against physical attacks and unauthorized entry.
