BoilerSupplies.com has the solution for your handhole and manhole plate needs. Many of the popular sizes are listed below, but if you do not see the size you need, call us and we can get it!

We carry both clip and stud style plates, which come with a neoprene handhole gasket with every plate. Stainless steel plates are available too!

All handhole and manhole plates listed are flat coded plates with the exception of the 11 x 15 which also has a non-coded version. Non-Code manhole assemblies have been proof tested to 600 PSI. These lightweight, single bolt and crab manholes have been designed for use in Non-Code vessels of low pressure, requiring frequent inspection and/or cleaning. Pressures should not exceed 15 PSI working pressure.

Fulton Upright Boilers use a Forged Steel Elliptical 3 x 4 plate. Integral Stud Type plates were originally used, later changed to Weld Stud Type (9” Radius and up) . We provide our customers with Forged Steel Handhole Plates for Fulton Boiler replacement plates. Patch plates are available, flat and curved.

*We also offer Original SIFCO Weld Stud Plates

We also recommend our Retro-Fit 3 x 4 Handhole Plates Assemblies which include a 3 x 4 Weld Ring and a flat handhole plate. This will replace all curved plates, when applicable.
