Gerda GD 900 Door Closer EN 3 Fixed Force Silver Fire Rated EN 1154

Product Overview

The Gerda GD 900 Door Closer is engineered for use on light interior doors in residential buildings and commercial premises. Featuring a precision-machined aluminum body and a steel arm, it meets EN 1154 standards, has a fixed EN 3 closing force, and provides fire resistance for more than 3 hours. Certified for 500,000 operating cycles, it is suitable for installations where consistent, maintenance-free performance is required even in demanding conditions ranging from -40°C to 45°C.

Distinctively, the GD 900 offers two-point adjustment for both closing speed (across 15°?180°) and latching force (0°?15°), allowing installers to fine-tune door control for specific safety or accessibility needs. This adjustability reduces installation risk and project rework for facility managers and building contractors, particularly for fire doors in apartments, offices, and public access buildings with variable user requirements.
