B-Harko H6 40g/40 Brass Cylinder Lock Thumb Turn Class 6 EN 1303 6-Pin

Product Overview

The B-Harko H6 40g/40 mm brass cylinder lock is intended for use in modern door installations, including residential and commercial interiors. Certified by the Building Technology Institute (ITB) to PN: EN 1303:2015-07, it achieves class 6.0 for durability and security, offering reliable performance across demanding environments with temperature resistance from -20°C to +80°C. The product includes a thumb turn (gałka) for easy locking and unlocking from inside.

The differentiation lies in its class 6 durability and security rating: tested for a minimum of 100,000 cycles and 100,000 key combinations, backed by corrosion resistance class C. This eliminates procurement risks for facility managers and OEM buyers seeking long-life, high-security cylinder locks for projects subject to intensive use and harsh conditions. Particularly suited for bulk purchasing in property developments, office complexes, and public-sector retrofits requiring substantiated compliance certificates.
