ITSMasticated Rubber Tie Pads

SHARE

Our founder Nelson Moses came up with this concept in 1937. While the concept is the same, the material has evolved into a highly engineered ROF (randomly-oriented-fiber) rubber, also known as masticated rubber. Our pads are on every class one system in the United States and also in Chicago and New York City Transits.
