Abstract: A seamless plastic shielding dasher board system includes at least two lower dasher boards each with a top sill having a plastic shield trough or channel therein for receipt and support of the plastic shield. A clear plastic shield a panel fits into the trough of each board. A clear, plastic, H-shaped shield panel support with open opposing support channels loosely receives the side edges of adjacent shield panels to permit linear and non-linear alignment of adjacent dasher boards and plastic shield panels. The shield supports have inwardly opposing lip projections at their open edges of the support channels to support the side edges of the shielding panels in vertical alignment.
