Patent abstract
A load support includes an outer tube and a plunger at least partially slidably disposed within the outer tube. Gravity-set wedging members are disposed between an outer surface of the plunger and an inner surface of the outer tube for setting the plunger and outer tube in place with respect to each other, wherein the wedging members are substantially self-setting under gravity. The wedging members gouge the outer surface of the plunger and the inner surface of the outer tube upon inward axial movement of the plunger within the outer tube.
