The dual level mounting bracket is used to mount 3 ducting systems at 2 different heights, on a common bracket; usually to allow cross over between the 3 ducting systems. Typically, optical fibre systems are at one level, with data and electrical systems at the others, so that crossover is achieved between the separate ducted services with minimum difficulty. It fits to standard Unistrut (TM) steel work, and is provided with a bolt, clamping nut & spring for that system.
