This 20-inch domed tank lid from Norwesco features a built-in gasket to create a secure, watertight seal. Its domed shape sheds rainwater, helping keep the tank free from surface water intrusion. It's made from UV-resistant polyethylene.

  • 20" diameter fits standard Norwesco manhole openings
  • Domed design helps prevent water pooling
  • Includes gasket for reliable, watertight sealing
  • Heavy-duty polyethylene for durability and UV resistance
  • Designed for compatibility with Norwesco extensions and risers
