WILKA 1400 40/50 + 1405 50g/40 Euro Profile Cylinder Set D-Grade EN 1303:2015 Nickel B-Class

Product Overview

The Komplet wkładek WILKA 1400 40/50 + 1405 50g/40 set consists of two keyed-alike Euro profile cylinders, one with double entry and one with an integrated thumbturn (gałka), both finished in matte nickel. Intended for security door applications in residential or commercial buildings, these cylinders meet EN 1303:2015 with resistance class B and are also certified for use in fire-resistant doors. Corrosion-resistant construction and high-cycle durability ensure reliability in both interior and exposed exterior locations.

The most distinguishing feature is the D-grade attack resistance paired with code security level 6 and minimum 100,000 real key combinations, delivering advanced mechanical protection against picking, drilling, and manipulation. This combination of physical and key security makes the set particularly well-suited for B2B buyers managing high-security access points in multi-unit complexes, institutional facilities, or public buildings, where long service life and certified intrusion resistance are project requirements.
