Gerda E1 35g/35 Cylinder with Knob Pearl Nickel PN-EN 1303 Class C Fire Door

Product Overview

The Gerda E1 cylinder insert 35g/35 with knob in pearl nickel finish functions as a high-durability locking core for mortise locks. It is certified to PN-EN 1303:2007, achieving at least 100,000 operating cycles and rated to corrosion class C, suitable for installation in both fire-rated and smoke-control doors. Operators include commercial building managers, facility maintenance teams, and contractors working in environments subject to heavy use and exposure to demanding temperatures from -20°C to +80°C.

A distinguishing feature of this model is its built-in knob, which streamlines controlled access without requiring a key from one side, eliminating a common failure risk in key-dependent systems and reducing user lockout incidents. This advantage is particularly valuable to buyers outfitting hotels, offices, or public facilities where quick, keyless egress and robust compliance with fire-safety norms are required. Ideal for bulk procurement in new-build or renovation projects for commercial, institutional, and multi-unit residential buildings.
