Manways and Inspection Hatches

Rectangular Manways

Download Data Sheet in PDF Format: 

Rectangular manways are used in a variety of different application from hygienic industrial washing machines, autoclaves through to solvent and chemical applications. 


Their shape lends itself perfectly to meeting a flat surface and consequently they are often the preferred choice for cubic vessels and tanks.  There is now a comprehensive range of sizes offered from small inspection ports through to the large 740mm x 540mm hatch that facilitates entry to vessels with breathing apparatus.


  • Sizes from 170mm x 225mm through to the 740mm x 540mm
  • Carbon steel neck rings and manways available to order
  • Special neck rings available for glass fibre and concrete tanks
  • FDA approved seals in EPDM, Silicone, Viton® or Nitrile
  • Many of our rectangular manways have also been up rated and pressures of up to 2.5 Bar are now possible
  • Alternative hinge mechanisms allow vertical and horizontal installation
