Abstract
A one-piece buoyant weir plate for use in skimmers for swimming pools and the like is formed from a rectangular sheet of expanded plastic or like material with closed cellular structure. The plate is subdivided into two panels by means of a heat-pressed hinge seam, and retained in the skimmer channel by means of a rigid mounting member holding one of said panels against the base of the skimmer channel while permitting the other panel to float upwardly and to act as a self-regulating weir when subjected to a pressure differential by the action of the filtering system pump.
