Abstract: The specification discloses a bracket system for positioning and supporting a component, such as a cladding panel (16), relative to the structure of a building. The system comprises brackets (18,20) fixed to the structure, each of which receives a support member (22) attached to the rear of a cladding panel (16).The brackets (18,20) disclosed include plates (38,40,60) defining an enclosure which receives a support member (22) and which is movable along one axis. The enclosure is shaped to restrict relative movement of the support member (22) along this axis while allowing relative movement along another, transverse axis. The support member (22) may include jack means to allow movement along a third axis.
