Product Overview

The WILKA 1400 30/40 + 1405 30g/40 cylinder set with knob is a security-rated lock cylinder suite designed for professional installation in commercial or residential entrances. Certified to EN 1303:2015 and WQ-ITB burglary resistance class B, these cylinders feature extended corrosion resistance and are permitted for use in fire-resistant doors. The set includes a double-sided cylinder and a knob cylinder with matched coding, plus five precision-cut steel keys, ensuring secure access control in demanding environments.
