NDS 1216 Catch Basin Riser for 12 Inch Square Catch Basin Drain and 12 Inch Low-Profile Adapter Drain, Black

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.

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.

This is a piece of plastic that does exactly what it’s supposed to.

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.

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

Great replacement. Easy to cut to desired height with bow saw.

Cut 3 inches off and screwed to the receiving lip and holds lawn mower running over no issue. 15 minute solution

This fits well and is plenty sturdy. It attaches to the basin with stainless screws, just like the original cover does. It does the job and was just the right height for my needs. I recommend the filter too, which you can also find on Amazon.

No issues.
