Hayward ASSY CONC ADJ W/CAP MDXR3 GRY

The Hayward Adjustable Concrete Assembly with Cap for the MDXR3 in grey is a 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 design 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. With its durable build and neutral grey finish, it provides a reliable, long‑lasting foundation for the MDXR3 drain system in contemporary concrete pool installations.
