About Malco Products

Malco Products, Inc. was founded in 1950 and was a market pioneer with its innovative specialty hand tools for the HVAC Trade (Heating, Ventilating and Air Conditioning).

Malco Products, Inc. got its start in 1950 when a young steel supply salesman, Mark W.Keymer, decided to manufacture and market a pipe crimper he had invented for use in installing the “new” sheet metal ductwork used with forced air heating systems. More tools soon followed, including: the first hand seamer to employ compound leverage; a time saving hand notcher that made a V-shaped cut in one motion; and a hand operated, snap lock punch to complete the basic sheet metal tool set. Metal duct fabrication could now be done easily at the job site and the tools were well received by contractor-installers.

In 1975 Malco also created a vital specialty tool market for Exterior Remodeling professionals (Installers of Roofing, Siding and Gutter) and is the market leader in that niche as well. Malco Productscontinues to lead and innovate by addressing a changing industry landscape and responding to emerging market needs for new specializations and more customized offerings.
