Hawke cable/pipe tolerant blocks have been designed with a degree of flexibility in order to accommodate variances in cable diameters. Additionally this flexibility enables each Hawke block size to accept a range of cable or pipe diameters.
Available in seven block sizes accomodating service diameters from 3mm to 100mm, Hawke blocks are marked with minimum and maximum cable diameters e.g. block size 3018 is marked with sizes 18/21 to signify that it will accept cable diameters from 18 mm up to maximum of 21 mm.
In practice this means that a small number of blocks can accommodate the full range of standard cable sizes. There is a less inventory to manage and the installation and inspection procedure is much faster and simpler than competing systems aided by the colour coding system.
