The Reln Series 410 Riser was designed to add 350mm to the Series 410 Pit's depth. In order for pits to cross with pipelines that are buried lower in the ground, risers are used. The requirement for a riser is independent of the slope of the terrain.

For business applications, such as driveways, parking lots, and trafficable areas, RELN Series 410 Heavy Duty Commercial Pits are the ideal surface water pits. The Galvanised Steel Class A Grate is ideal for use in pedestrian-friendly areas and light commercial applications.
