Product Overview

The dormakaba C-Lever K6 Pro is an advanced electronic door handle set designed for access control on exterior and high-security doors in commercial and institutional environments. Manufactured in Switzerland, it is certified to EN 16867, EN 1634-1 and -3 for fire and smoke resistance, as well as EN 179 and EN 1125 for emergency escape routes. The unit supports door thicknesses of 35?63 mm, features an 8 mm spindle, narrow backplate (39.8 mm wide), and achieves IP55 moisture resistance for reliable performance outdoors or in challenging environments.

The inclusion of real-time access management for virtually unlimited users, with compatibility for LEGIC, MIFARE, NFC, and Bluetooth Low Energy, distinguishes this handle from standard electronic access solutions. This eliminates the risk of administrative bottlenecks or outgrowing the access system, supporting future-proof investments in large-scale institutional or multi-site commercial deployments. It is particularly suitable for projects in schools, hospitals, care homes, and industrial facilities requiring high user capacity and seamless system integration.
