TriStar D400 straight bar gully grates

Captive hinge

Wrekin has developed its most competitive gully grate to date.
The new 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 450mmØ 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.
