Oval cover and suspension arm

The oval cover opens inward and is linked to an external suspension arm. Support lugs and a bridge bracket form part of the mounting and closure arrangement. The oval opening and external arm distinguish the assembly from round covers and linked rectangular-frame designs.

Central screw and operating handle

The illustrated closure includes a central screw, hub and spanner-style handle. These parts work with the bridge bracket and suspension arm as a complete assembly. Confirm the required handle configuration and retain access to the operating point when locating nearby tank fittings.

Materials and selected size row

The frame and cover list 304 or 316L stainless steel, with a silicone gasket in the illustrated parts list. The dimension chart covers oval sizes from 430×330 to 635×525 and contains two 530×430 entries with different collar thicknesses. Use the complete selected row to distinguish these configurations rather than identifying them by the size name alone.

Tank-side installation and access

The welded collar is described mainly for the tank side. Plan the opening orientation and the space for the inward-moving cover and external arm together with vessel internals and adjacent equipment. Routine inspection should include the visible support and closure components and gasket seating area; replacement parts need the matching oval profile and configuration.
