Armadillo gully grate shells safeguard gully tops installed against the kerb at finished road level (up to 50mm proud of the surrounding construction surface) from the extreme loads presented by construction plant traffic, prior to the application of finish road surfacing.
It is a reusable or if necessary sacrificial accessory for loose [or optional clamp] fitment over Wrekin TriStar 430x370mm and 450x450mm gully grates.
Armadillo gully grate shells also inhibit coarse debris from entering the gully, protecting the pot and drainage system.
