Supergrit and Red Hill Corporation

Arturo Ottolenghi started his weekend business out of his garage in Cleveland, OH in 1978. He sold Supertack hot melt glue sticks for electric glue guns. In 1985, Arturo added Supergrit Abrasives to the line and devoted full time to Red Hill. The business thrived, and in 1995 Red Hill built a 22,000 sq ft office, store and warehouse in Gettysburg, PA.
