TriStar D400 Gully Grates

The TriStar ductile iron hinged gully addresses many issues related to cost-effective products. The frame has been designed to suit all existing gully pot styles and will sit over a typical 450mm Ø circular or horseshoe chamber.

The frame has been designed with an anti-debris feature to stop the backfill material entering the chamber. This range of D400 Ductile Iron gully grates fully comply with BS EN 124:2015 and carries the British Standard Kitemark.

The captive hinge allows for a single unit opening with anti theft feature.

Years of exceptional performance

Our Highway D400 covers are still operating at full capacity after three and a half years of being subjected to high levels of HGV traffic. Meaning the organisation can focus solely on new work, rather than being distracted by manhole covers that have failed prematurely and need fixing or, in some cases, reinstalling.
