Winkhaus N-tra 30/50 Cylinder Lock Nickel Class 6.2 C Anti-Pick Patented Key

Product Overview

Winkhaus N-tra 30/50 nickel-plated cylinder lock is a double-sided cylinder for doors, commonly specified for residential and commercial security installations. Certified to class 6.2 C, it features a paracentric keyway profile and provides enhanced protection against unauthorized key duplication and manipulative opening techniques. Each cylinder includes three drilled keys with a patented design protected until 2029, giving procurement managers assurance on intellectual property security.

The key differentiating feature of this model is its dual system of security pins: 6 spring-loaded wafers per side, plus up to 8 horizontal blocking elements without springs. This advanced combination significantly reduces the risk of lock-picking and bumping attacks, which is critical for projects demanding elevated anti-manipulation security. This product is particularly suited for bulk security hardware procurement in multi-family residential or office building projects where certified high-security cylinders are mandatory.
