Abstract
A coupling assembly for connecting first and second members of a helical pile system. A coupling member has a first opening at a first end and a second opening at a second end. A hollow protrusion extends outwardly from and axially along the outer surface of the coupling member. A fastener opening is disposed in the coupling member. A first member is fixedly receivable by the first opening of the coupling member. A second member has a rib disposed on an outer surface. The rib is receivable by the protrusion when the second member is received by the second opening of the coupling member. A fastener is receivable in the fastener opening. The fastener prevents withdrawal of the second member after being inserted in the coupling member.
