From the 19th century, the Bigelow Company in New Haven, CT, had made boilers for stationary and marine applications, many used throughout much of the country.
Over the past century, Bigelow Boilers have used a wide variety of handhole plates. Below are some common plates we have come across. We strongly recommend a detailed inspection of the handhole plate being replaced and the application to compare with our stock.
