Abstract
A low profile downspout extension is formed in multiple segments including a flexible conduit, a splash block and an extension. The splash block transitions from a circular inlet into a low profile pentagon configuration with a central bead along the top surface of the low profile body portion to define an apex of the pentagon shape. The body portion is wider than the diameter of the circular inlet but has a height at the central bead that is more than half the diameter of the circular inlet. The body portion has ribbed side walls to strengthen the splash block without requiring internal reinforcement. The bottom surface of the splash block defines a flow path that extends generally linearly from the bottom of the inlet opening to the bottom of the pentagon-shaped outlet. An open configuration for the splash block provides an alternative above-ground splash pad structure.
