Hayward ASSY CONC ADJ W/CAP MDXR3 BLK

The Hayward Adjustable Concrete Assembly with Cap for the MDXR3 in black is a durable main‑drain sump designed for concrete pool construction, allowing installers to precisely set the height and position of the MDXR3 drain before the concrete is poured. Its adjustable structure helps ensure the drain sits flush with the finished pool surface, supporting proper hydraulic performance and alignment with modern safety requirements. The included protective cap keeps the sump opening clean and correctly sized during construction, preventing debris from entering and preserving the drain’s placement. The black finish offers a sleek, modern look that blends well with darker pool interiors while providing a strong, long‑lasting foundation for the MDXR3 drain system.
