Available in seven block sizes accomodating service diameters from 3 mm to 100 mm, Hawke Blocks are marked with minimum and maximum cable diameters e.g. block size to accept cable diameters from 18 mm up to maximum of 21 mm.
In practise this means that a small number of blocks can accomodate the full range of standard cable sizes. There is less inventory to manage and the installation procedure is much faster and simpler than competing systems.
