Abstract

A channel for fluid flow comprising a first unit and a second unit connected to each other. The first unit comprises a first u-section having a first open top side, and a first grate extending across the first open top side and removably attached to the first u-section. The second unit comprises a second u-section having a second open top side, and a second grate extending across the second open top side and removably attached to the second u-section. The first grate defines a negative semicircular distal end having a first diameter and a first center point. The second grate defines a positive semicircular proximal end having a second diameter and a second center point. The first center point is coincident with the second center point and the first diameter and the second diameter are sized such that the positive semicircular proximal end fits within the negative semicircular distal end.
