The rectangular trunking (2) has a number of bosses (12) along one side. A first folded strip is fixed to the ceiling using screws or other fastening devices (22). The second folded strip is fastened to the bosses (12) by bayonet screws (13). The second strip is laid into the first and attached with snap-in fastening pins (38). The trunking has rear tap-off apertures which allow cables to exit and be laid along (34) the strip until the cable destination is reached. |
