Outward-opening access cover

The round cover opens outward from its welded collar and is connected by hinge components. A separate cover handle provides an identification feature alongside the perimeter hand rings. Consider the opening direction and handle position when comparing this assembly with other round tank manways.

Hand rings and spring hardware

The closure arrangement uses hand rings with hubs, swing bolts, springs and washers, supported by lugs and retaining parts around the collar. These are distinct components in the illustrated assembly. Match replacement hardware to the complete closure configuration rather than selecting only by hand-ring appearance.

Frame, cover and size options

The frame and cover list 304 or 316L stainless steel and the illustrated gasket is silicone. Six size rows are shown from 300 to 600. Compare the selected row for collar and cover dimensions, especially where thickness differs by size; a picture of one size does not define every configuration.

Layout and service planning

The welded interface, outward cover path and surrounding equipment must fit the intended tank location. Leave access to the hand rings and cover handle. Routine maintenance can include checking the visible springs, retaining hardware and gasket seating area, with replacement materials and seals selected for the actual assembly and process conditions.
