Gerda EVO 35g/30 Cylinder Lock Satin Nickel 12 Tumblers EN 1303 Class 5.1 B with Knob

Product Overview

The Gerda EVO 35g/30 satin nickel cylinder lock with knob is used in high-security residential and commercial door assemblies demanding advanced anti-burglary protection. Certified to PN-EN 1303:2015-07 (class 5.1 B), it features anti-bumping and anti-drill protection, making it suitable for fire-rated joinery according to ITB evaluation. Hardened steel pins and a brass body ensure durability and long-term reliability even in demanding environments.

A key differentiator is the innovative key profile with 12 tumblers (9 in two rows plus 3 side tumblers), offering 9,300,000 possible key code combinations. This significantly reduces procurement risks related to unauthorized key duplication and guarantees restricted access for facilities with strict access control policies. Particularly suitable for bulk installation in multi-tenant buildings, fire-rated doors, and security-focused commercial properties.
