The Hawke colour coded block system provides total inspectability of the transit installation even after assembly has been completed. 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.
On a major installation many hundreds of insert blocks are used. As no modification of the Hawke Transit System insert block is required the system is fast and easy to install and eliminates installer modification errors.

The tape enables cable diameters to be accurately measured thus ensuring that the correct size of block is selected for the cable diameter.
The gauge is wrapped around the cable this then details the correct block to select for that cable together with the colour coding.
