Less ring means the plate and yoke assembly is sold without the reinforcing ring, which is typically kept in place since it's already welded to the boiler shell.
What is the difference between elliptical and obround handhole plates?
Elliptical and obround describe the shape of the opening the plate covers, with the correct shape depending on the boiler manufacturer's original design.
Do handhole assemblies differ by boiler brand?
Yes. Handhole and manhole assemblies are typically matched to a specific boiler manufacturer, such as Burnham, Fulton, or Johnston, since bolt pattern and curvature vary by brand.
What does flat vs curved mean for handhole plates?
Flat plates are designed for flat sections of a boiler shell, while curved plates match the radius of a specific boiler diameter, so confirming the shell's curvature helps ensure a proper seal.
