The B-Harko H6 35/35 mm cylinder lock is a double-sided brass euro profile insert designed for modern residential and commercial doors. Certified by the Building Technology Institute (ITB) to PN:EN 1303:2015-07, it achieves class 6.0 durability and security, with demonstrated resistance to corrosion and temperature extremes from -20°C to +80°C.
