Product Overview

The B-Harko H6 45/50 mm Euro profile cylinder is a 6-pin door lock insert designed for professional installations in modern residential and commercial interiors. Certified by the Building Research Institute (ITB) to PN: EN 1303:2015-07, it achieves class 6.0 for durability, security, and corrosion resistance, supporting at least 100,000 cycles and key combinations. Operating reliably from -20°C to +80°C, it meets key requirements for high-use environments and is supplied with three solid brass keys.

What distinguishes the B-Harko H6 is its classification code 1 6 0 0 0 C 6 0, providing maximum cycle and corrosion durability (Class 6, Class C), along with high torque resistance of 15 Nm.
