Gerda E1 30g/40 Cylinder Lock with Knob Euro Profile Brass Class C Fire Door EN 1303

Product Overview

The Gerda E1 30g/40 cylinder lock with knob is a Euro profile cylinder for use with mortise locks, intended for interior and exterior doors in residential and commercial buildings. It meets the PN-EN 1303:2007 standard, ensuring reliable performance and suitability for high-traffic environments. This model is approved for use on fire and smoke-proof doors, making it compliant with stringent safety regulations commonly required in public and commercial facilities.

A key differentiator of this cylinder is its highest corrosion and temperature resistance rating (Class C), which assures durability in settings with fluctuating temperatures and moisture exposure.

It is particularly suitable for bulk procurement by contractors outfitting multi-unit residential, hotel, or institutional facilities requiring compliance with fire safety codes.
