WILKA 1400 K423 Cylinder Lock Insert 55/60mm Class C EN 1303:2015 Anti-Drill Brass

Product Overview

The WILKA 1400 K423 55/60 cylinder lock insert provides high-security door locking for residential or commercial buildings, featuring classification in the highest security class C and compliance with EN 1303:2015 standards. Outfitted with a six-pin mechanism, paracentric key profile, and components hardened with a nickel coating, it is suitable for use in fire-rated doors and environments demanding lengthy resistance to physical attack and tampering. Each cylinder undergoes durability testing exceeding 100,000 cycles, meeting grade 6 longevity standards.

A distinguishing feature is the inclusion of anti-drill hardened steel pins in both the body and plug, providing 5?10 minutes of resistance against drilling, mechanical attacks, and pulling. This significantly reduces the security risk for procurement in high-theft or sensitive access areas. Recommended for security-focused B2B buyers, especially those outfitting critical facilities or requiring class C cylinders for regulatory compliance in institutional and public sector projects.
