2" (5.1 cm) Round Corner Square Extensions

Extensions range from 3.5 feet to 10 feet in length. The integral forged socket coupler is a bolted connection to the installed lead or extension with helix and the anchor installation resumed. Extensions with helix are placed directly after the lead section (no bare extensions in between). They are used when additional bearing area is needed and to develop increased installation torque. The extension torque rating must match the rating of the lead section.

Hot Dip Galvanized per ASTM A123.


A complete Power Shaft assembly consists of a lead helix section, extension(s) and guy termination other attachment.  The helix size (diameter) and number of helices are selected for the required holding strength.  The shaft size and rating is selected based on the necessary holding strength and installation torque requirement.  The guy attachment is chosen based on the number of guys.
