    Waste—Drains to Waterways

    Message

    Made of cast iron, these covers are strong enough to handle high-volume foot and vehicle traffic. Use them to cover manholes on roads, parking lots, or walkways.
    Gasket—Covers with a gasket are used on sanitary manholes. They prevent sewage water from leaking out and contaminating surrounding ground water.
    ADA Compliant—Covers that are ADA Compliant prevent narrow wheels from getting stuck since they have 1/2" wide slots.

    Designed to support heavy loads, these grates are used to cover drains in sidewalks and roadways. Since they only require support on the two long sides, you can install them end-to-end over a long stretch.
    Choose a grate with a DIN load class rating that's suitable for your application.
    Style 1—Style 1 grates have small openings, so narrow shoe heels won't poke through or get stuck.
    Class A—Class A grates are best for areas with foot traffic, bicycles, and carts.
    Class B—Class B grates are suitable for areas with light vehicle traffic, such as driveways and parking lots.
    Class C—Class C grates can handle heavy truck traffic in roads and commercial zones.
    Class E—Class E grates are designed to withstand impact from heavy vehicles with solid tires, such as forklifts and cargo planes.
