A shelf support system comprises a shelf support arm (1) adapted to be mounted horizontally and a support bar (5) adapted to be disposed vertically and means for mounting the support bar (5) to a vertical wall or other support surface, sliding means enabling the arm (1) to slide up and down the bar (5) and retaining means to secure the arm (1) to the bar (5) at any desired position. The retaining means include a resiliently expandable member (6) held by the arm (1) so as to be frictionally engageable with the bar (5) by operation of actuating means (9, 10) to expand the member (6) towards the bar (5). <IMAGE> |
