The invention provides a stud of any chosen length. The stud has a plurality of sections (preferably two or four), each of which extends for substantially the length of the stud. The sections may be capable of moving relative to one another in a horizontal or vertical direction. In one embodiment, the sections of the stud are adapted to be fixed by fixing means, such as screws, expanded locking mechanisms and ratchet arrangements.
