Modular aerial trunking for carrying services, i.e. cables and fluid supplies

摘要

The trunking network carries service cables and service fluid in triangular sub-compartments situated within the corners of the triangular cross-section telescopic trunking which has perforated sides. The sub-compartments are secured by nylon clips and vibration is prevented by semi-rigid pads stuck between the sub-compartments and telescopic trunking. The telescopic trunking may be jointed or brought to octagonal junction boxes. The octagonal junction boxes have a wooden base and sheet metal sides and are supported by triangular cross-section vertical columns. Half junction boxes may be attached to buildings. The structures are made from painted sheet metal or coated aluminium.
