Product Overview

The B-Harko H6 40/40 mm cylinder lock is a 6-pin euro profile insert tested by the Building Technology Institute (ITB) in accordance with PN: EN 1303:2015-07. Used in residential and commercial doors, this lock conforms to class 6.0 durability, security, and corrosion resistance, delivering at least 100,000 cycles and working reliably from -20°C to +80°C.
