Winkhaus N-tra 45/45 Cylinder Lock Nickel Security Class 6.2 C Patented Key System

Product Overview

Winkhaus N-tra 45/45 nickel cylinder lock is a symmetrical double-sided security insert used in commercial, institutional, or residential environments requiring certified protection. Certified to class 6.2 C, it offers advanced resistance to tampering, manipulation, and unauthorized key copying, making it well-suited for access-controlled facilities. Each unit includes a patented drilled key system valid until 2029, providing added assurance against unlicensed duplication.

The primary distinguishing feature is the multi-layered anti-manipulation and anti-drilling protection, achieved through six springless locking pins per side plus additional reinforced pins and stainless steel elements. This eliminates common procurement risks associated with security hardware in high-risk or access-controlled installations, particularly satisfying demands for protection against picking, drilling, and key duplication. Recommended for security upgrades, bulk procurement for property management, and OEM access control projects requiring verified certification and patented key systems.
