Industrial Boiler Doors - 24" Diameter Heavy-Duty Access Doors with Refractory

OVERVIEW
 
Heavy-duty industrial boiler access doors salvaged from large commercial steam boiler. Professional-grade door assemblies measuring approximately 24 inches in diameter with substantial refractory lining and insulation. Complete hinged door construction with robust steel frame and bolted closure mechanism. Features multiple layers of refractory brick insulation for high-temperature applications. Light blue exterior paint finish with weathered patina. Substantial construction suitable for high-pressure, high-temperature boiler applications. Door assemblies include full refractory lining with multi-layer insulation system visible in interior views. Ideal for boiler repair, restoration projects, industrial furnace applications, or salvage for refractory materials and heavy steel components.
