Hayward ASSY CONC ADJ W/CAP MDXR3 WHT

The Hayward Adjustable Concrete Assembly with Cap for the MDXR3 in white is a purpose‑built 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 both proper hydraulic performance and compliance with modern safety standards. The included protective cap keeps the sump opening clean and correctly sized during construction, preventing debris intrusion and preserving alignment. With its durable construction and clean white finish, it provides a reliable, long‑lasting foundation for the MDXR3 drain system in new concrete pool builds.
