Winkhaus N-tra 40G/35 Cylinder Lock Nickel Class 6.2 C Extended Key Shoulder

Product Overview

The Winkhaus N-tra 40G/35 nickel cylinder lock is a high-security euro profile lock designed for commercial, institutional, and residential door installations requiring certified protection. Supplied with a certified class 6.2 C rating, this cylinder features a robust internal mechanism including both roller and non-spring horizontal blocking pins, as well as hardened steel anti-drill elements. Each unit includes three patent-protected drilled keys, ensuring improved resistance against unauthorized key duplication up to 2029.

A distinguishing feature of this model is its extended 13 mm key shoulder, enabling compatibility with a wider range of security escutcheons and allowing for more diverse door assembly combinations. This reduces procurement risk for facility managers and door hardware suppliers dealing with varied site specifications. Particularly suitable for bulk procurement in security-sensitive commercial and institutional environments, where certified lock quality and key management are required.
