ABSTRACT:
An improved banner pole structure includes a first cylindrical tube, a pole head, a second cylindrical tube, and a bias frictional assembly. The pole head is threadedly coupled to the first cylindrical tube and the first cylindrical tube is telescopically received within the second cylindrical tube. The bias functional assembly is coupled to an end of the first cylindrical tube and frictionally engages an interior wall surface of the second cylindrical tube, responsive to rotation of the first cylindrical tube relative to the second cylindrical tube.
