Gerda E1 28/36 Cylinder Insert Nickel Pearl Class C Corrosion PN-EN 1303:2007

Product Overview

The Gerda E1 28/36 nickel pearl cylinder insert is engineered for use with mortise locks in commercial and residential doors. Certified according to PN-EN 1303:2007, it provides high durability with a minimum of 100,000 operating cycles and achieves class C for corrosion resistance, functioning reliably between -20°C and +80°C. Approved for installation in fire-rated and smoke-control doors, this insert is suitable for demanding interior and exterior environments, particularly where safety and longevity are project requirements.

A key differentiator of the Gerda E1 28/36 is its class C (highest) corrosion resistance and wide operational temperature range, which minimizes maintenance risks and ensures consistent performance in harsh conditions. This feature is particularly important for buyers specifying hardware in facilities exposed to temperature changes or humidity, such as industrial sites and public buildings. It is recommended for bulk procurement in high-traffic commercial projects or any application where fire and smoke compliance is mandatory.
