GERDA HSS 632Z Padlock Concealed Shackle Security Class 4 PN-EN 12320:2013-04

Product Overview

The GERDA HSS 632Z padlock features a concealed shackle design and disk locking mechanism, specifically engineered for securing commercial and industrial spaces such as warehouses, gates, and grids. With certification to PN-EN 12320:2013-04, security class 4, and corrosion resistance class 3, this padlock has been tested by the Institute of Precision Mechanics and the Central Forensic Laboratory of the Police for robust security. The Hard&Soft System (HSS) technology combines tough and soft materials to maximize resistance against mechanical attacks including cutting, twisting, and forced entry.

Its standout feature is the concealed shackle construction, which significantly reduces the risk of unauthorized cutting or leverage attacks compared to standard padlocks. This design offers added protection for installations exposed to tampering or high security risks. Recommended for facility managers and bulk procurement in logistics, property management, and professional security applications where certified high-security padlocks are required.
