Product Overview

B-Harko H6 30g/35 mm cylinder lock is a 6-pin door insert manufactured from brass with a thumbturn, certified to PN: EN 1303:2015-07 and tested by the Building Technology Institute (ITB). It meets class 6.0 for durability, corrosion resistance, and high security, with a temperature tolerance from -20°C to +80°C. Intended for modern interior doors in residential and commercial buildings, it comes with a robust 2.3 mm brass key and is supplied with three keys per cylinder.

The primary feature distinguishing the B-Harko H6 from standard cylinders is its class 6 classification: guaranteed at least 100,000 cycles, high key security (minimum 100,000 combinations), and resistance to corrosion and extreme temperatures. This reduces maintenance risk and supports compliance with strict facility specifications. Facility managers and project procurement teams needing long-life, secure cylinders for high-traffic installations will find this product well-suited for bulk procurement and specification-driven projects.
