Permanent mark protection cases, aerial view marking materials
If particularly important markings be exposed to strong mechanical loads in the ground, we recommend the use of protective boxes or conduits, which are cast around or above the marking bolts.
The size and type of protection depends on the value of the item and the control procedures provided.
All enclosures and conduits have a spring-loaded lid open. The lid can be opened with a strong cross-head screwdriver or other mandrel.
