This access hatch creates a hidden opening in Gyptone Base 31 ceilings, meaning you can carry out checks and maintenance without compromising on aesthetics. The Gyptone Base 31 Hatch does away with unsightly service openings by seamlessly blending in with surrounding tiles. It has an acoustic backing to absorb noise, and it also improves indoor air quality using ACTIVair® technology. The hatch comes in a two-part system that's quick and easy to fit, including a frame and a plain 510mm tile.
