Slant/Fin was founded by Mel Dubin in 1949. Mel was convinced there was a better way to manufacture fin-tube radiation and he was determined to find it. Mel’s story (and eventually our story) started in the back of a bakery in Coney Island, New York, with a focus on commercial grade elements. The original design was a locked, slanted fin - hence the name Slant/Fin. Mel had lots of stories - his favorite about the small original work area. "We had to manufacture 10-foot elements one-half at a time, then open the back door to turn it around to finish." For more than half a century, heating contractors, engineers and builders alike have depended on Slant/Fin for products of the highest quality.
