WILKA 1400 45/55 + 1405 45g/55 Cylinder Set EN 1303:2015 D Class B Keyed Alike Matte Nickel

Product Overview

The WILKA 1400 45/55 + 1405 45g/55 Euro profile cylinder set provides high-security access control suitable for commercial, institutional, and high-risk residential buildings. Both the double-sided and knob cylinder are finished in matte nickel and support keying-alike operation, allowing one set of 5 dimple-cut keys to open all included cylinders. Certified to EN 1303:2015 with grades 1 6 0 B 0 C 6 D and burglary resistance class B (WQ-ITB), these cylinders are approved for use in fire-rated doors and demonstrate exceptional endurance and corrosion resistance.

The key differentiator is the highest possible attack resistance rating "D" under EN 1303:2015, combined with anti-picking mushroom pins and hardened steel elements that protect against drilling attempts. This notably reduces procurement risk for projects where mechanical security certification and proven tamper-resistance are specified, such as critical infrastructure or regulated access zones. The set is particularly recommended for security integrators, facility managers, and bulk buyers delivering standardized security hardware for multi-door installations.
