Winkhaus N-tra Master Key System 10 x 30/30 mm Cylinders Patented Profile Nickel EN 1303

Product Overview

The Winkhaus N-tra Master Key System is a complete cylinder set designed for controlled access in commercial and institutional buildings. This package includes ten double-sided 30/30 mm nickel-plated cylinders, thirty individual keys (three per cylinder), and three master keys that operate all cylinders. All cylinders comply with DIN 18252 and EN 1303 standards, and each system is supplied with a Winkhaus security card encoding key and access information for owner-authorized duplication or expansion.

The differentiating feature of this SKU is the use of patented key profiles and the dedicated security card, which restricts unauthorized key copying and system modifications. This setup greatly reduces procurement and operational risks in B2B environments, ensuring access control integrity across multi-site installations. Particularly recommended for property managers and facility owners seeking scalable, managed-key systems for medium-sized commercial buildings or institutional projects.
