Slant/Fin is America's largest manufacturer of baseboard heating equipment. We are also one of the top manufactures of gas and oil boilers. Since 1949, heating contractors, engineers and builders have depended on Slant/Fin for products of the highest quality. Our heating equipment is installed in millions of homes in the United States, Canada and aroundt he world. Slant/Fin was founded by Mel Dubin in 1949. It was started in the back of a bakery in Coney Island, NY. When the company started its focus was commercial grade element and the original design was a locked, slanted fin, hence the name Slant/Fin. One of Mel’s favorite stories is about how small the original work area was. When they were making 10 foot element they had to manufacture half the element at a time, then open the back door to turn it around to finish.
