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.
An aluminum datum point is usually used instead of a domed cap and an access cover would usually be fitted to protect the mark.
