"Specialized Geometry for Perimeter Curb Inlets."
The D-Shape Riser is a precision-engineered solution for curb-back manholes and drainage structures. Designed with one flat side to sit flush against the concrete curb head, these risers allow for seamless asphalt resurfacing around complex perimeter geometries without obstructing the gutter line.
The flat side is precision-machined to ensure a tight, no-gap fit against existing concrete curbs, preventing asphalt seepage into the basin.
Features integrated seat-locking lugs to prevent the riser from rotating or shifting under the pressure of a steam roller.
Finished with industrial-grade bituminous paint to withstand the extreme temperatures of fresh hot-mix asphalt.
