Product Overview

B-Harko H6 40g/45 mm Euro profile cylinder with knob is used in interior and exterior residential and commercial door locks requiring enhanced security and durability. Certified by the Building Research Institute and compliant with PN: EN 1303:2015-07, it meets stringent requirements for durability (class 6), corrosion resistance (class C), and key security (class 6), allowing installation in environments with high usage cycles and varying temperatures (-20°C to +80°C).

What distinguishes this model is its class 6.0 durability and key security (over 100,000 cycles and at least 100,000 key combinations), minimizing risk of service calls and unauthorized access for facility managers and procurement teams. Suited for projects requiring standardized high-security cylinders and bulk installation, particularly in new apartment blocks, hotels, or institutional buildings with strict hardware specification requirements.
