Frame & Grate 9x9

Frame and grate floor drain, 9 × 9 inch (approx. 230 × 230 mm), in heavy-duty non-corrosive ABS, fixed with stainless steel screws. Used as a main drain cover in concrete pools and as a floor outlet in balance tanks, plant rooms and deck areas. The frame is cast into the concrete and the grate drops in flush, so it can be lifted for cleaning without tools. The open area is large enough to keep suction velocity low across the whole grate, which is what entrapment-safety practice requires of a pool main-drain cover.
