摘要:
A sealing plate (2), for use with a rail clip anchoring device having a head and a stem which extends from the head into a concrete sleeper when the anchoring device is in use, wherein the plate is adapted for extending over the underside of the head when the stem of the device is being set in a concrete sleeper, thereby to prevent ingress of concrete into the head of the device, and for being retained on the surface of the sleeper thereafter, and a face (20) of the plate which is to be exposed on the surface of the sleeper is not adapted to receive part of a rail clip.
