This monument consists of four separate components: cap, extension rod, lockscrew and driving rod.
Where Single Rod is required without threaded hole - see Triple-Fluted Stakes
Rod ends each have threaded hole and lockscrew installed in one end
Both ends are protected by plastic end caps
Surv-Kap extension rods feature machine-faced and precision drilled and tapped ends to freely accept every lockscrew. A high nickel and chromium stainless steel alloy lockscrew securely fastens the Extension Rod to the Driving Rod. Please call for custom rod lengths.
