Helping The World Sort Things Out.
Dual Manufacturing Co., Inc. is located in Franklin Park, Illinois. For over 65
years we have produced a variety of high quality products including sieves,
scales, measuring devices, sample splitters, storage
containers, screens, crucibles,
beakers & much more. Our commitment to quality and service have been the cornerstone
of our company since it began in 1942.
Here at Dual Manufacturing we also offer lab equipment for testing asphalt, concrete
or soil and are proud to produce the finest and most accurate testing sieves made
today. This commitment to quality takes extra effort, but we won't do business any
other way. For more than four generations our family-owned business has dedicated
itself to giving our customers the best selection of test sieves available anywhere and products that are 100% American made.
