Gerda E1 25/25 Double Cylinder Insert Satin Nickel PN-EN 1303:2007 Fire Door Rated

Product Overview

The Gerda E1 25/25 cylinder insert is used with mortise locks in access doors for residential and commercial premises. Certified to PN-EN 1303:2007 (classification: 1 6 0 1 0 C 2 0), it provides a tested minimum lifespan of 100,000 cycles, high corrosion resistance (Class C), and operates within a temperature range from -20°C to +80°C. Fire and smoke door approval ensures compatibility with enhanced safety requirements.

A defining feature of this specific SKU is its double-sided 25/25 mm dimensioning, which fits doors where equal insertion lengths on both sides are necessary. This minimizes the risk of improper fit during procurement for standardized doors and streamlines installation, especially useful for contract work in properties with uniform door thickness. Particularly recommended for bulk orders in residential developments and for retrofit projects in fire-rated building zones.
