Gerda GD 1000 Door Closer EN 2/3/4 Silver Dual Adjustment Fire Rated 1100mm

Product Overview

Gerda GD 1000 Door Closer delivers controlled closing for interior and exterior doors in both residential and commercial buildings. It features a fixed closing force rated EN 2/3/4, working reliably in temperatures from -40°C up to 45°C. Certified to EN 1154 and endurance-tested for 500,000 cycles, it is suitable for doors up to 1100 mm wide and up to 80?85 kg weight depending on model, and provides over 3 hours of fire resistance to meet safety requirements in high-traffic and fire-rated applications.

The distinguishing feature of this model is its dual screw adjustment system, which allows independent regulation of closing speed and final latch force within defined angular ranges.
