Hygienic Rectangular Tank Manhole Covers are specialized access ports commonly installed on the side-walls of large storage vats and mash tuns. Their wide, horizontal profile allows for easy removal of solid residues, such as spent grain or fruit pulp. Designed for outward-opening, they feature a smooth, radius-corner frame to prevent bacterial buildup. Made from 316L Stainless Steel, they provide a robust, leak-proof seal for non-pressurized or low-pressure vessels.
