B-Harko H6 Master Key Cylinder System 10x 30/30mm Brass EN 1303:2015-07 30 Keys

Product Overview

The B-Harko H6 master key cylinder system features ten brass lock cylinders (size 30/30 mm) and thirty identical solid brass keys, allowing multiple rooms to be operated with a single key. Each cylinder has been tested by the Building Research Institute (ITB) for compliance with PN: EN 1303:2015-07, classification 16000C60, and is rated at durability class 6 (minimum 100,000 cycles), suitable for use in residential and commercial buildings where secure and convenient access management is required.

What sets this system apart is the provision of a full set of 30 identical keys for 10 cylinders, eliminating the logistical challenge of key duplication for facility managers or landlords. This simplifies distribution and replacement processes, making it highly suitable for hotels, offices, multi-unit residential properties, and educational facilities requiring consistent and efficient access control.
