Boiler Supplies carries a large selection of handhole and manhole parts. Products can be viewed by manufacturer or by size. Handholes are small manholes that are not big enough to be used for access but become helpful during boiler inspections and washing. Handholes are often replaced and are available in a variety of sizes depending on the boiler.

A manhole is much larger than a handhole, and is large enough for a worker to access and enter part of the boiler.
