315mm Dia Shallow Access Chamber Riser (185mm Invert)

This 315mm shallow access riser is designed to raise the height of a 315mm chamber assembly where additional adjustment is required to meet paving or finished surface levels. With an 185mm invert reference, it suits shallow chamber applications and helps reduce on-site adaptation.

A useful component for both new build and refurbishment projects where final landscaping levels are confirmed after initial drainage installation.
