Gerda E1 30g/50 Cylinder Insert Brass With Knob EN 1303 Class C Fire Door Use

Product Overview

The Gerda E1 30g/50 brass cylinder insert is designed for use with mortise locks in a variety of door assemblies, including fire- and smoke-rated models. Certified to PN-EN 1303:2007, it withstands at least 100,000 operating cycles and achieves the highest corrosion resistance class (C), making it suitable for heavy-duty use in both residential and commercial applications. Temperature resistance ranges from -20°C to +80°C, supporting reliable function in challenging environments.

This specific SKU features an integrated turn knob, which streamlines emergency exit requirements and user convenience compared to standard key-only cylinders. That single-sided knob design reduces procurement risk in projects requiring fast egress or regulatory compliance for escape routes, especially in multi-unit residential blocks or institutional buildings. It is particularly well-suited for professional procurement by facility managers and contractors outfitting fire- or smoke-protected doors.
