- With the elastic cushion rail plate, plate specifications and materials should meet the design requirements. Before tightening the bolts, rail and elastic plate tightly; When there is a gap, the plate should be added in the elastic pad under, pad length and width shall be 10 ~ 20 mm than the elastic plate.
