If your catch basin is at an odd height, there’s an easy way to fix that. Just dig out a little deeper and add a riser.

FDM’s 6 in. Catch Basin riser adds 5 inches of height. If you need more than 5 inches of lift, simply stack the risers on top of each other and build to your desired height. We also sell a shorter 6 in. Riser with 1.5 in. of lift.

Both of our 6 in. risers are interchangeable. For example, if you need to lift your basin 6.5 inches, you could stack one Riser with 5 in lift and one Riser with 1.5 in lift, as opposed to stacking 4-5 of the shorter risers.
