Whether your application calls for 2” or 36”, our risers can be stacked to meet your needs. Working with different diameter openings? Not a problem! Our risers come in three different diameters that enable you to use them for a majority of applications. If you are retrofitting a system, our adapter rings are an ideal, simple to use, solution that allow you to convert your system to accept Polylok risers and covers. When safety is a concern, consider including our riser pans. They nestle into the riser stack and enable you to use a concrete plug to minimize unwanted access.
