Marine Round Transits System

MCT’s – Standard

The Hawke Round Transit System is designed for the sealing of cable and pipes that pass through circular openings providing an effective seal against fire, gas, water, etc.

The HRTO version is an open version for applications where the cables/pipes are already installed.


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.

Manufactured in zero halogen materials.

Hawke is the only colour coded system for the blocks, which allows you to check if the two halves of the block have been correctly selected by the installer.
