<p>A terminal box (1) is attached to the channel section cable support rail (7) by a three-piece clamp. The end wall of the terminal box (1) forms one part of the clamp and has an S shaped hook (11) which can grip either an external flange (1) or an inwardly turned flange. The other two pieces (2, 6) fit one inside the other and have hooks (61, 34) for gripping outwardly turned flanges whilst the piece (6) has a hook (62) for gripping inwardly turned flanges. The box (1) can thus be used with either type of cable support rail.</p> |
