Works well for raising catch basins.
Worked well for raising several catch basins that had over time become low as the grass grew around it. One of the best features is that the riser can be cut to fit the existing catch basin.

Quality and perfect fit
It was a perfect fit with the basin I had installed years ago and very bit as sturdy. It comes with screw holes, but no screws. I chose to add sealant between the riser and the original basin but there is not as much flat surface contact between the riser and the basin as I expected. All in all though, it was exactly what I needed. A sturdy solution to the problem of a basin that was just too low.

Perfect fit!
I installed this today with the separate grille that I had purchased. Easy install - no issues.

Expensive.
Exactly what I needed, but unfortunately NDS products are a bit on the expensive side. You would be better off using your creativity skills and making your own insert.

This item took forever to get delivered. I ordered it June 27, 2025 and it was finally delivered September 5, 2025. Other than that, the product looks fine.
