Gerda PRO System X WKM4 Euro Cylinder 45/45 Satin Nickel Class D High Security

Product Overview

The Gerda PRO System X (WKM4) 45/45 satin nickel profile cylinder is a high-security euro-cylinder engineered for mortise locks in both residential and commercial doors. Certified to PN-EN 1303:2015-07 with a classification of 1 6 0 B 0 C 6 D by the Instytut Mechaniki Precyzyjnej, it meets rigorous mechanical strength, durability, and anti-burglary standards. The cylinder is approved for use in fire-rated (p.poż.) and smoke-control doors and is suitable for installation in environments exposed to temperatures from -20°C to +80°C.

This Gerda PRO System X version?s core advantage is its resistance class D?the highest available?offering at least 5/10 minutes of drilling and mechanical attack resistance due to integrated components like hardened steel anti-drill pins and a reinforced anti-burglary bar. This substantially mitigates procurement risk for B2B buyers requiring proven burglary resistance in compliance with insurance or legal mandates. Recommended for security-sensitive applications in public buildings, high-value residential complexes, and commercial fire or smoke-rated door installations.
