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.

All values stated are nominal within 2.5% tolerance.
