Flared Ends:

Flared ends connect to concrete pipe as inlets and outlets for storm water ponds and culverts under roadways and approaches. They come in a range of sizes for 300mm–1500mm concrete pipe and have sloped ends. For larger pipe sizes of 1650mm–2100mm pipe, a concrete box bevel with a cast in pipe adaptor is available.

Round grates are also available with and without a gate for pipe and flared ends. Round grates help to keep animals out and prevent debris from entering the storm system.
