On each of the two exposed block faces minimum and maximum diameters are clearly marked. This indicates the specific sealing range of the block size.

Each individual block has a colour coded face, this ensures that each size and pair of tolerant block halves is always correctly matched to the cable diameter. Hawke´s unique inspectable colour coded blocks ensure that the top and bottom half of each block has been correctly matched for size.

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 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.


Hawke Blank Filler Blocks

Filler blocks are available in the same materials as the tolerant Blocks. They are used to fill spaces within the frame which are not required for services, thus allowing spare capacity for future requirements.


Hawke Standard Tolerant Blocks

This enables a wide range of cable or pipe diameters to be accommodated by a compact range of tolerant block sizes.

Hawke tolerant blocks have five sealing faces that are displaced by the sealing process. This results in a tolerance of up to 4 mm for cable diameters.



Hawke Trefoil Insert Blocks / Hawke Special Insert Blocks

Hawke Trefoil Insert Blocks: These blocks allow three single phase power cables to be sealed inside of the same cable block. *Available in 90mm and 120 mm size*

Hawke Special Insert Blocks: When Hawke Transit System Frames are penetrated by services that are shaped anything other than circular, eg. busbars, special cables, earthtraps, etc. Special EMC bocks can be manufacturer. Please contact our Sales Department for more information.


Hawke Wave Guides

Hawke manufacture a range of blocks to suit the most popular waveguides sizes. Hawke wave guide insert blocks are used inserted in Standard HF Blocks.
