Notes

The wedge seated frame has been designed to suit all existing gully pot styles and will sit over a typical Ø 450mm circular or horseshoe chamber opening. The frame flange has reduced apertures as a mortar guard to stop backfill material from entering the chamber.

The use of Armadillo is recommended where exposure to construction site traffic is likely.

The D400 load capability of these Group 3 products also offers the benefit of making them suitable for exposure to Group 4 traffic types. Where 3-flange D400 Gully Grate assemblies are employed, we recommend that they are installed against a kerb, not in an open highway location.
