LOB WP600 DRAGON XT Euro Cylinder Lock 40/55mm Class D EN 1303 High Security

Product Overview

LOB WP600 DRAGON XT 40/55 is a high-security euro cylinder lock designed for commercial and residential applications with heightened security requirements. Tested by the Institute of Precision Mechanics in Warsaw according to PN: EN 1303:2015-07, it fulfills security class 6 D, offering exceptional durability (minimum 100,000 cycles), anti-corrosion properties (class C, -20°C to +80°C), and is approved for installation in fire-rated door assemblies.

Its most distinguishing feature is the highest attack resistance rating (class D), including 5/10 minutes resistance against drilling and mechanical attack, which minimizes risk in environments requiring certified, extended break-in protection. This makes the WP600 DRAGON XT 40/55 especially suited for bulk procurement by security-focused public facilities, banking, and corporate office construction projects where compliance and long-term reliability are mandatory.
