ABSTRACT:
A slope adjustable head for an adjustable pedestal (10) for supporting beams, panel members, typically pavers, in accurate edge aligned relation, in a level plane is disclosed. The pedestal (10) includes a base block (12) and a series of inter-engaging threaded annular elements (20, 30) which can be rotated relative to each other to adjust the height of the top of the pedestal in a screw jack fashion. A slope compensator is located at the top of the pedestal and comprises a slope compensation plate (100) and a head member (50). Rotation of the slope compensation plate (100) about its center of curvature causes the angle of the adjustment plate relative to the vertical axis to change thus allowing for compensation for the slope of the surface on which the pedestal is standing.
