We have to go back to 1950 to find the beginning of Malco Products, when a young steel salesman, Mark Keymer, came up with a wonderful idea for the new sheet metal duct industry. He designed a pipe crimper that would aid in the installing of these ducts for forced air heating systems. It became a hit and soon afterwards, and he started to design more products for HVAC. Pretty soon, out of a garage, Malco tools were born. Now, more than 50 years and several expansions later, Malco tools is an industry leader in hand and HVAC tools. In addition, Malco is working on becoming an industry powerhouse in the exterior remodeling industry with their line of roofing, siding and gutter tools. By continuing the company tradition of innovation and leadership, Malco Tools is meeting and exceeding the needs and demands of their consumers.
