Gerda E1 50g/35 Cylinder Lock Insert with Knob Class C Corrosion Nickel Pearl EN 1303

Product Overview

The Gerda E1 50g/35 Double Cylinder Insert with Knob is a profile cylinder lock core designed for use with mortise locks in commercial and residential doors. Manufactured to the PN-EN 1303:2007 standard, it ensures a minimum lifespan of 100,000 operational cycles and maintains resistance to both corrosion and a broad temperature range from -20°C to +80°C. The insert is approved for installation in fire-rated and smoke-control doors, making it suitable for compliance-driven environments.

What differentiates this model is its class C (highest) corrosion resistance, which significantly minimizes maintenance needs and replacement cycles especially in high-humidity or exterior-exposed applications. This advantage reduces operational risk and ensures long-term cost efficiency for facility and asset managers. The Gerda E1 50g/35 is ideal for building contractors and procurement officers handling bulk installations in environments requiring fire and smoke door compliance, such as public buildings, offices, and multi-family housing developments.
