B-Harko H6 30g/50 Cylinder Lock Insert Satin Nickel Class 6 Durability Knob EN 1303

Product Overview

B-Harko H6 30g/50 mm is a cylinder lock insert with satin nickel finish and integrated knob, tested and validated by the Building Technology Institute (ITB) against PN: EN 1303:2015-07. Designed for modern interior doors, it is used in residential and commercial environments requiring advanced security and durability. The classification 1 6 0 0 0 C 6 0 guarantees the product meets class 6 standards for durability, corrosion resistance, and key security.

The key differentiator is its class 6 rating for both durability (100,000 cycles minimum) and key security (minimum 100,000 key combinations), significantly reducing risk for facility managers and OEM buyers handling medium- to high-traffic installations. Its verified corrosion resistance (class C) makes it a strong option for buildings with variable temperature and humidity. This lock is particularly well-suited for bulk procurement in office, hotel, or residential development projects needing certified, high-performance locking hardware.
