Gerda GD 500 Door Closer EN 3 Silver Fire Rated >3 Hours EN 1154 Certified

Product Overview

The Gerda GD 500 Door Closer is designed for modern residential and commercial spaces, supporting fire-rated doors up to 950 mm wide and 65 kg. Certified in accordance with EN 1154 and rated for over 500,000 operation cycles, it maintains performance in demanding, high-use environments and within a broad temperature range from -40°C to 45°C. Fire resistance exceeds 3 hours, making it suitable for locations with heightened safety requirements.

Unlike basic door closers, the GD 500 stands out with its certified fire resistance above 3 hours, reducing risk in buildings where compliance with stringent fire safety protocols is non-negotiable. This capability eliminates the need to source separate, specialized models for fire barrier doors, streamlining procurement for property managers and contractors. Particularly well-suited for bulk use in multi-unit housing projects, office corridors, or public buildings requiring both compliance and cost efficiency.
