A support member system includes a set of elongate members (2). Each elongate member (2) has a first end (53) and a second end and a predetermined length. The predetermined length of each elongate member (2) is different from the predetermined length of each of the other elongate members (2). An end member (10) has an elongate member engagement portion (12, 13) adapted to engage with the first end (53) of an elongate member (2), and a support structure engagement portion (15). The support structure engagement portion (15) is adapted to engage with a support structure (8). The elongate member engagement portion (12, 13) permits the distance from the wall engagement portion (15) to the second end of the elongate member (2) to be adjustable at least up to the length of the next longer elongate member (2) in the set.
