Gerda E1 28/36 Profile Cylinder Brass PN-EN 1303:2007 High Durability 100,000 Cycles

Product Overview

The Gerda E1 28/36 brass cylinder insert is designed for integration with mortise locks requiring a high-durability profile cylinder. Used widely by building contractors and locksmiths in both commercial and residential settings, it is certified to PN-EN 1303:2007 and approved for installation in fire-rated and smoke-proof doors. This model offers corrosion resistance class C and is rated for a temperature range of -20°C to +80°C.

A key differentiator of the Gerda E1 28/36 is its minimum endurance of 100,000 operating cycles, which exceeds basic standards and assures longevity under frequent use. This extended durability mitigates the risk of premature cylinder failure in high-traffic facilities and lowers long-term maintenance costs. It is particularly suited for refurbishment projects, public buildings, and any scenario requiring a certified insert for fire and smoke protection doors.
