When road construction changes a road’s grade level, access to manholes and catch basins can become problematic or a source of complaints due to potholes and uneven pavement. But how can you get back up to grade? One option that helps solve the problem is using riser rings. Here's a quick overview to get started:

When the grade increases around your access points and grates, the face of the frame ends up lower than is usable for your cover. Riser rings are available in a range of heights to help bridge the gap between the old cover or grate and the new one. These lightweight riser rings are very easy to install, helping your work crews save time when retrofitting the existing frames. They’re available in round and square shapes to match your existing systems access points.

Manhole Riser Ring

How do you find out what size riser ring you need for installation? To get the best possible fit for your manholes and catch basins, know the specifics about the application. Providing the following information will help you get there:

  • The cover diameter or grate dimensions.
  • Height of the grate or cover that needs to be increased.
  • Thickness of the cover or grate.

It is vital to provide the most accurate information possible to ensure that you get the riser ring you need for the job.
