Winkhaus N-tra NT04 N 45G/60 Euro Cylinder Lock Thumbturn kl. 6.2 C Patent Key 2029

Product Overview

The Winkhaus N-tra NT04 N 45G/60 is a double cylinder euro profile lock insert with a thumbturn, designed for use in commercial and residential doors where advanced security is required. It is supplied with three side-milled, horizontally symmetrical keys and achieves security rating kl. 6.2 C, meeting stringent requirements for physical security. The insert features anti-pick elements, hardened steel anti-drill pins, and a paracentric keyway profile for enhanced protection.
