Upgrade your pool’s filtration with the U.S. Pool Supply Wide-Mouth Thru-Wall Skimmer Kit, a professional-grade solution designed for maximum debris removal and long-term durability. Engineered as a high-performance replacement compatible with the Hayward SP1091WM, this universal kit fits most major above-ground pool brands, providing a permanent, leak-proof skimming solution that far outperforms temporary "over-the-wall" models. Crafted from UV-resistant, high-impact ABS plastic, the housing is built to endure harsh weather, intense sun, and pool chemicals without cracking or fading. The weighted weir door creates a continuous surface draw, capturing leaves and floating debris before they sink, which reduces strain on your pump and keeps your water crystal clear. With a complete set of stainless-steel hardware, double gaskets, and a vacuum plate included, you have everything needed for a fast, DIY installation that eliminates the need for expensive service technicians. Can I use this skimmer on a soft-sided pool? This is designed primarily for steel-walled above-ground pools. While some users modify soft-sided pools to accept thru-wall skimmers, it requires permanent cutting of the liner and extra reinforcement which is not officially supported. What size hose does the vacuum plate use? The included vacuum plate adapter is designed to fit standard 1 ¼" and 1 ½" pool vacuum hoses, allowing you to clean the pool floor using the skimmer's suction.
