Product Overview

The B-Harko H6 Euro profile cylinder lock is a 35/35 mm double-sided cylinder designed for modern door installations requiring certified security and durability. Frequently specified for residential and commercial applications, this lock cylinder carries the PN: EN 1303:2015-07 certification, confirming compliance with rigorous European standards in both locksmith and architectural projects. The product is tested by the Building Research Institute (ITB), achieving durability class 6 with a lifecycle rating of at least 100,000 operating cycles and features a matte black finish for contemporary interiors.
