The JUMBO MANUFACTURING P-325-512 is a cast iron drain grate measuring 5.5 inches, designed to cover floor drain bodies in commercial and residential plumbing applications. Cast iron construction provides long-term durability under heavy foot traffic and exposure to water, debris, and common cleaning chemicals. This grate serves as the visible, load-bearing cover seated over a floor drain body, allowing water to pass through while blocking larger solids. Installation is handled by licensed plumbers or qualified maintenance personnel during new construction or drain service work.
This drain grate is suited for use in floor drain assemblies found in mechanical rooms, laundry areas, commercial kitchens, utility spaces, and similar wet environments where reliable drainage is required. The 5.5-inch diameter fits drain bodies sized to accept this grate. It is a straightforward replacement or new-installation component for any drain body that accepts a 5.5-inch cast iron grate.
Designed as an OEM-style replacement or new-installation cast iron drain grate for floor drain bodies accepting a 5.5-inch grate.
Installation and replacement of floor drain grates is typically performed by a licensed plumber. Shut off water supply and ensure the drain is clear before servicing the drain body or seating the grate. Verify the drain body opening diameter matches the 5.5-inch grate size before installation. Local plumbing codes (IPC) may govern floor drain placement and specifications in commercial applications.
