B-Harko H6 Cylinder Lock Brass 6-Pin EN 1303 Class 6 Knob 60g/60mm

Product Overview

The B-Harko H6 cylinder lock is a six-pin brass door insert designed for use in residential and commercial interiors requiring high levels of security and durability. Certified by the Building Research Institute (ITB) to PN: EN 1303:2015-07, it meets class 6.0 performance with at least 100,000 operating cycles and offers resistance to corrosion and extreme temperatures from -20°C to +80°C. The lock comes with a convenient knob operation and solid brass keys.

What distinguishes the B-Harko H6 from standard Euro-profile cylinders is its top-grade classification in durability (100,000 cycles) and key security (minimum 100,000 combinations) per EN 1303. This eliminates procurement risk for buyers seeking hardware for demanding projects requiring advanced, tested security and extended service life in potentially harsh environments. It is particularly suited for bulk installation in new-build commercial offices, multi-residential properties, and facility renovation projects where certification and documented performance are required.
