Product Overview

The B-Harko H6 Euro profile cylinder lock with knob (size 25g/35 mm, satin nickel finish) is a 6-pin cylinder certified to PN: EN 1303:2015-07 by the Building Research Institute (ITB). It is rated to class 6.0, offering the highest durability and key security for use in modern residential and commercial doors. The product is engineered for high traffic environments and is suited for interior and exterior installations due to its resistance to corrosion and wide operating temperature range.
