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 Catch Basin riser adds 2 inches of height. If you need more than 2 inches of lift, simply stack the risers on top of each other and build to your desired height.
Fits any of FDM’s 4″ Pop-Ups and FDM’s 4″ Catch Basin.
