TriStar™ gully grates

D400 Straight Bar, 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 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.
