Top Grates Flat for Box Culverts

Flat Top Box Grates are designed to mount on top of box culvert inlet or outlet structures to keep debris from entering the storm water system. Works well where some pedestrian traffic is expected and can be secured to limit access. Hinges are mounted to one side of the concrete structure to allow the entire grate to open and gain full access to the structure.

  • Clean and durable plate style design
  • Full access side hinge
  • Galvanized steel construction. Can be made from aluminum or stainless steel.
