ABSTRACT:
A section of trunking (20) has sides (22) which define a channel (34). Edge portions (32) of sides (22) are shaped so as to form further channels (34); Lid (26) has surface (29) and edge portions (30) which extend over channels (34) so as to form enclosed volumes. Screws (36) are used to fix lid (36) onto trunking section (20). Any water leaking through holes (38) and down the threads of screws (36) will be retained within channel (34) and will eventually dissipate between the side portion (30) of lid (26) and side (22) of trunking section (20). Trunking sections (20) are coupled by coupling (50) which is formed from surfaces (52, 54, 56, 58, 60, 62 64and66) which themselves engage internal surfaces of the trunking sections and their respective lids. Coupling (50) is provided with pairs of threaded holes.
