Winkhaus N-tra 30/30 Cylinder Lock Nickel Class 6.2 C Double Sided 12-Pin Security

Product Overview

The Winkhaus N-tra 30/30 nickel double cylinder profile lock offers advanced mechanical security for commercial and residential doors, featuring a symmetrical design and horizontal dimple key system. Certified to class 6.2 C standards, it meets demanding requirements for tamper resistance and durability in high-traffic or security-sensitive environments such as offices, apartment buildings, and institutional facilities.

A key differentiator of this model is its combination of up to 8 springless horizontal blocking pins alongside 6 pin tumblers per side, which substantially increases protection against both manipulation attacks and forced entry. For bulk procurement or facility management requiring patent-protected key duplication control and robust attack resistance, this model is particularly suitable.
