¾" Aluminum Datum Point w/ Thread
Where a rod monument is to be used for precise vertical measurements, the top section is encased in a grease-filled plastic sleeve, thus isolating the rod from any movements of the surrounding soil. The sand backfill also helps in this process.
A aluminum datum point is usually used instead of a domed cap and an access cover would usually be fitted to protect the mark.
