WILKA 1400 40/50 + 1405 40g/50 Cylinder Set EN 1303 6/D Brass Class C Security Keyed Alike

Product Overview

The WILKA cylinder set 1400 40/50 plus 1405 40g/50 with knob is a high-security lock insert kit intended for use in commercial and residential doors requiring advanced intrusion protection. Both cylinders meet EN 1303:2015 and WQ-ITB class C burglary resistance, and are certified for fire-rated doors and extended durability across 100,000 test cycles. Brass and hardened steel construction with a paracentric keyway improves resistance to tampering and forced entry attempts in high-risk environments.

The key differentiator of this set is its compliance with the highest EN 1303 attack resistance and code security grades (level 6/D), offering protection against picking, drilling, and physical attack for 5/10 minutes. Strict control of key copying through an accompanying security card eliminates unauthorized duplication risk, which is crucial for facility managers and project purchasers securing sensitive access zones. Especially suited for institutional, banking, and managed office buildings where B2B buyers require certified, tamper-evident security hardware delivered as a master-keyed or one-key system.
