Malco Products, SBC, got its start in 1950 when Mark W. Keymer, a young steel supply salesman, decided to manufacture and market a pipe crimper he had invented for installing the “new” sheet metal ductwork used in forced air heating systems. Today, the legacy of that exciting start-up company lives on and the early Malco tools have since been joined by hundreds of other specialty products.Shop All Malco Products ProductsVisit Malco Products Website
