<p>The electrical trunking (10) has a base (11), optionally with internal mounting rails, with side-walls (13) ending in turned-in lips (15). The rolled-over lip edges provide channels (18) into which are clipped the beaded rims of cover-plates. One channel also accommodates the snap-on securing and ribs of retaining clips (22), lying under the covers. Each clip, integrally moulded, has a main body (23), connected by a thin flexible hinge (28) to a short plate (26) terminating in the securing end-rib. In normal service the hinge is closed, with the clip top trapped behind the upper lip. Access, without removing the clip completely, is obtained by slipping the free end past the flexible top lip and folding down(F1) at the hinge.</p> |
