A utility port for a desk, table or the like comprises a central column (3) extending through apertures (8) in respective modules (1, 2) arranged for rotational movement about the column (3). The periphery of each aperture (8) is formed with projections (9) which coact with selected ones of channels (22) in a sleeve (13) to prevent relative rotation between modules (1, 2) and sleeve. Further formations on the sleeve (13) prevent relative rotation between the sleeve and a baseplate and a desk to which the base plate is connected. The arrangement enables the modules to be rotationally fixed in one of a number of relative rotational positions with respect to a desk upon which they are supported. |
