110mm Square Hopper Riser

This square hopper riser is designed to extend the height of compatible square hopper assemblies, allowing installers to match the hopper top to the final surface level. It’s particularly useful on projects where drainage is installed before paving depth and finished levels are fully confirmed.

Used in both new-build and refurbishment settings, the riser helps reduce the need for on-site adaptation and supports a neat fit around external drainage details.
