Datum plates are fixed to structures (bridges, platforms and overhead line masts, etc.) that are located near the track. The details on the plate specify the relative position of the track from said structure, which can then be monitored for movement.
Our datum plates are supplied with a green or red block free of cost. Please specify which variation you require using the drop-down menu above.
PLEASE NOTE: The price shown above is for a single item; if you are looking to purchase in bulk, please get in touch!
