Extension, RS3500.300, 14/14/14 X 10ft long 3 hole pattern

A helical pile is a segmented deep foundation system with helical bearing plates welded to a central steel shaft. Segments or sections are joined with bolted couplings. Installation depth is limited only by soil density and practicality based on economics. A helical bearing plate or helix is one pitch of a screw thread. All helices, regardless of their diameter, have a standard 3" pitch. Being a true helical shape, the helices do not auger into the soil but rather screw into it with minimal soil disturbance. Helical plates are spaced at distances far enough apart that they function independently as individual bearing elements; consequently, the capacity of a particular helix on a helical anchor/pile shaft is not influenced by the helix above or below it.

• Round Shaft Lead Sections are assembled to Round Shaft Extension with through bolt(s).
• The helical shaped plates do not auger into the soil but rather screw into it with minimal soil disturbance
• Hot dipped galvanized per ASTM A153
• Capacity of pile can be determined my measuring installation torque
• Bolt and nut are assembled to extension at the factory
