Product Overview

The Gerda E1 35g/40 cylinder insert with knob in pearl nickel finish is built for integration with mortise locks in access doors. Manufactured for both residential and commercial use, it is certified according to PN-EN 1303:2007 standards, offering a durability rating of at least 100,000 cycles, high corrosion resistance (Class C), and operating reliability from -20°C to +80°C. Approval for installation in fire-resistant and smoke-control doors supports compliance in regulated building environments.

The primary differentiator of this model is its highest corrosion resistance rating, Class C, which ensures extended longevity in demanding or unpredictable climates, eliminating risks related to premature mechanism failure due to rust. This makes the Gerda E1 35g/40 particularly suited for facility managers and procurement for public, multi-unit, or industrial buildings where reliability and certification are critical procurement criteria.
