B-Harko H6 Euro Profile Cylinder 30/30 mm Matte Black 6-Pin EN 1303 Class 6 Durability

Product Overview

The B-Harko H6 30/30 mm Euro profile cylinder is a high-durability lock cylinder intended for use in residential and commercial doors where both security and longevity are critical. Manufactured with a matte black finish, it is independently tested and certified by the Building Research Institute (ITB) to the PN: EN 1303:2015-07 standard, achieving class 6.0 for durability, corrosion resistance, and key security. Suitable for modern interiors requiring reliable, aesthetically compatible hardware.

A distinguishing feature is the cylinder?s maximum class 6 durability classification, guaranteeing at least 100,000 operating cycles and class C corrosion resistance (operating reliably from -20°C to +80°C). This specification reduces the risk of premature wear or locking failure in high-traffic or harsh environmental conditions, making it a strong choice for facility managers and procurement for multi-unit residential, office complexes, or public buildings that demand robust performance and security.
