Product Overview

The Gerda E1 40g/50 Euro cylinder lock with brass knob is engineered for integration with mortise locks in residential and commercial doors. Compliant with the PN-EN 1303:2007 standard and certified for fire-rated (p.poż.) and smoke-control (dymoszczelnych) door use, it offers durability of at least 100,000 cycles and resists corrosion per the highest Class C rating. Operational reliability is ensured within a temperature range from -20°C to +80°C, supporting applications in variable climate conditions without degradation.

A distinguishing feature of this model is its brass thumbturn knob, which allows quick manual locking/unlocking from the inside?reducing the risk of locked-out scenarios and supporting safety-focused procurement for hotels, offices, and public buildings. This makes the E1 40g/50 particularly suited for bulk installation in new-build and retrofit projects where secure, code-compliant access and interior egress convenience are both required.
