As of 2016, we have grown by three fold and continue to expand our footprint and product offering. Allied Rubber and Supply, an industrial distributor, has gone through a number of changes since its founding in 1973. Originally known as Three Rivers Tool and Supply, four employees and a 1000 square foot warehouse were the entire company. In 1988, Three Rivers Tool and Supply became Western Pennsylvania Rubber and Supply. A 6800 square foot warehouse and office were constructed and the focus of the company changed to become a full line, year round force in the marketplace versus a seasonal supplier of fleet products.
