These Duco coated cast iron unfinished floor cleanouts are installed in areas where their large 8-1/2” (215) access cover is desirable and the appearance of cast iron is satisfactory. They are available with a cast iron medium duty (fig. 4313) cover or non-tilt heavy duty (fig. 4318) cover and can be adjusted to level the top with adjacent flooring. They are fitted with a bronze taper thread closure plug and flashing collar.
