<p>The square supports have offset attachments, and may be rotated to achieve required positioning. The lighting rail comprises a C-shaped rectangular section profile (1) with a base (11) and two sides (12,13). Folded edges (14,15) lie parallel to the base and complete the C-shaped rectangular section. Each electrical fitting is mounted on a base plate (2) which slides inside the rail, retained by the folded edges. A receiver is mounted on each plate in order to accommodate the electrical fitting. This receiver is shifted w.r.t. the centre of symmetry (O) of the plate. By inserting the base plate in one of four different orientations, the electrical fitting may adopt a variety of different positions w.r.t. the rail.</p> |
