Unite D400 Gully Grates

Our premium Unite D400 gully grate combines new technology with proven features to deliver a super long-life and the lowest whole-life cost of any D400 gully grate.

The inclusion of a lower secondary grid promotes pedestrian and cycle safety whilst disrupting surface water flow to maximise the volume evacuated. The three-way hinge design enables it to be installed in any orientation and optional safety stays resist uncontrolled closing.
