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. Top Security rod is available in 3/4" (19mm)  diameters. The Top Security design provides excellent 3-dimensional stability.
