• The range
Compared to its siblings
Against Double Slot, Single Slot trades flow capacity for the tightest possible sightline - pick it when the drain needs to disappear into the paving. Against Ductile Iron, it's the lighter-duty, more discreet option; Ductile Iron takes over where vehicular load or heavy foot traffic makes a robust cast grate the safer choice.
