Gerda E1 36g/28 Euro Profile Cylinder Thumbturn PN-EN 1303 Nickel Satin Fire Door

Product Overview

The Gerda E1 36g/28 Euro profile cylinder with thumbturn is engineered for integration with mortise lock mechanisms across commercial and residential buildings. Certified under PN-EN 1303:2007, it delivers a minimum durability of 100,000 operating cycles and achieves class C for corrosion and temperature resistance. Its construction allows use in fire and smoke-proof door assemblies, making it a compliant option for regulated environments.

A key differentiator for this model is the inclusion of a thumbturn on one side, simplifying secure and fast egress without a key in high-traffic or emergency exit applications. This feature minimizes operational risk for facility managers and installers seeking to meet both usability and fire code requirements. It is particularly suited for bulk procurement in institutional and hospitality projects where certified, user-friendly door hardware is essential.
