Abstract: The present tenter frame chain includes a plurality of links, each link including upper and lower interconnected loadbearing plates, and a low friction slide block sandwich between the upper and lower interconnected plates. The slde block is formed of material having a lower coefficient of friction than the interconnected loadbearing plates and includes a vertically disposed bearing surface located laterally outwardly beyond the lateral extent of one side of the upper and lower interconnected loadbearing plates. The vertically disposed bearing surface of the slide block contacts the bearing surface of the guide rail to reduce the frictional rubbing movement of the tenter chain against the vertically disposed bearing surface of each of the tenter chain guide rails as the tenter chain moves therealong.
