B-Harko H6 Euro Cylinder Lock 40/40mm 6-Pin Class 6 Durability EN 1303 Satin Nickel

Product Overview

The B-Harko H6 40/40 mm cylinder lock insert is a 6-pin, double-sided euro profile cylinder designed for modern interior and entrance doors. Certified by the Building Research Institute (ITB) according to PN: EN 1303:2015-07, it meets class 6.0 standards for durability, corrosion resistance, and key security?suited for high-traffic residential and commercial use in challenging environmental conditions.

This model's main differentiator is its highest classification in both durability (class 6 ? minimum 100,000 cycles) and corrosion resistance (class C), which significantly reduces the procurement risk for buyers needing hardware suitable for extended lifecycle and exposure to harsh temperatures (from -20°C to +80°C). It is specifically recommended for facility managers, OEMs, and distributors sourcing locks for multi-unit developments, offices, or public buildings with strict durability requirements.
