B-Harko H6 Euro Cylinder 55/60mm 6-Pin EN 1303 Class 6 Nickel Satin Finish

Product Overview

The B-Harko H6 55/60 mm Euro profile cylinder is a six-pin door lock insert tested by the Building Research Institute (ITB) and certified to the latest PN: EN 1303:2015-07 standard. Used in modern interior residential and commercial doors, it delivers high security and durability in conditions ranging from -20°C to +80°C. Classification 1 6 0 0 0 C 6 0 confirms superior corrosion resistance and security, meeting class 6.0 requirements for demanding applications.

A major differentiator of this cylinder is its class 6 durability rating, guaranteeing at least 100,000 operating cycles. This reliably eliminates maintenance risk and replacement frequency for bulk installations where longevity is critical, such as apartment building access control or office fit-outs. It is particularly well-suited for professional locksmiths, multi-unit property managers, and B2B procurement for new construction or renovation projects requiring certified security hardware.
