The Skimmer Grille prevents your pool skimmer from being blocked. It keeps larger items out without restricting water flow. It conceals hardware and makes the faceplate look like new. The skimmer grille increases the speed of water at the opening for better skimming. The model G-IGWM-H fits most in ground widemouth skimmers, including: Hayward® SP1085, American Products, Aquador® 1085, Custom Molded, Waterway, and others.
