Product Overview

The Gerda E1 45g/45 knob cylinder is a euro-profile lock insert designed for use with mortise locks in both fire-rated and smoke-control doors. Intended for commercial and residential installations, it carries the PN-EN 1303:2007 certification with top corrosion resistance (class C) and a durability rating of at least 100,000 operating cycles, enabling use in demanding environments including high-traffic areas subject to fluctuating temperatures from -20°C to +80°C.

This particular model features an integrated thumbturn on one side, which simplifies emergency egress and key management compared to standard key-key cylinders.
