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.

I used this for a French drain system I put in at our cottage. It is a solid and sturdy product. Does the job.

Not much to be said here. This is made of thick plastic and replaced a really old drain gate that had gotten brittle with pieces starting to break off everytime you needed to lift the gate. Fit perfectly, with the screw hole also perfectly aligned. Very affordable, perfectly sized, durable replacement. 5 stars all day.

This grate works great! Fits the drain I have perfectly. Water drains just like it should. Not a bad price either!
