This is a 21″ Gloxco Carbon Steel Manway Assembly typically used as a hatch on vacuum trucks, trailers and other vacuum tanks.
The 21″ size is the perfect size to replace existing 20″ manways. When a 20″ manway is cut out, our 21″ manway will be a better fit for the hole and will make for an easier installation.
This manway assembly has a carbon steel lid and a 6″ carbon steel neck. It is unpainted and includes six(6) Gloxco wingnut assemblies and a buna manway gasket.
