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

Product Overview

The Gerda E1 40g/40 cylinder lock with knob is intended for use with mortise locks in commercial and residential doors. This profile cylinder is certified to PN-EN 1303:2007, achieving a minimum durability of 100,000 cycles and features the highest corrosion resistance rating (class C). It is approved for installation in fire-rated and smoke-control doors, making it suitable for demanding interior environments and regulated access points.

A distinguishing feature of this SKU is its integrated brass knob, which simplifies operation from one side of the door and reduces the need for a separate thumbturn accessory. For procurement teams and project managers, this minimizes errors during specification and installation, especially in large developments with varying access control needs. Well-suited for fire safety door projects, new builds, and bulk-residential retrofits where compliance and installation efficiency are key.
