Product Overview

WILKA 1400 K423 double-sided cylinder lock, finished in satin nickel, provides advanced access security for commercial and residential doors requiring high resistance to physical attack and manipulation. Built to class C and certified under EN 1303:2015 and WQ-ITB standards, it is approved for use in fire-resistant doors and environments demanding enhanced durability and anti-corrosion performance.
