¾" Aluminum Top Security™ Rod Monuments

The Top Security Rod Monument System is a unique concept in monumentation.  The monument is composed of a drive point, sectional extension rod(s), Top Security finned rod, and a compression-fit or screw on cap.  All components are metallurgically-matched for resistance to corrosion.  A most unique feature of this monument is the solid aluminum "Y" shaped Top Security finned rod that provides added horizontal stability to the monument structure.

These are exactly the same as the rod monuments, except that, for the top section a security rod with three aluminum fins is used.  This increases the stability of the mark.  All sections of the monument, including the top security section can be driven straight into the soil or the top section can be isolated from the topsoil as shown below. 

The fins of the top security section can be peeled back with vice grips if it is necessary to cut the top section.  This enables the cap to be tapped on.
