摘要

The device has a compensation spacer (1) made of magnetic or magnetized rigid material and comprising a central hole (12). An internal metallic projection of a rail (3) is located at the level of a fixation hole and is housed in a counterbore for positioning the spacer, when the spacer is placed on a point to be installed inside the rail. The counterbore is provided at the level of the central hole. The width of the spacer is less than that of the rail.
