Avoid the Risk

The main function of our Hawke Transit System is to maintain the integrity of a firewall, bulkhead or deck through which cables, pipes and other services pass.

The Hawke Transit System is the only totally inspectable system on the market.

Our Tolerant Blocks use a colour coding system to minimize incorrect installation. This feature is unique to Hawke Transit System.

Also, the min and max cable O/D is clearly marked on the block as to which that particular block will seal. Both features enable post inspections of installed transits, increasing the safety and reliability of the installations.

At Hawke, safety comes first.

Both the design and manufacture of the Hawke Transit Systems are made with safety in mind first.

Hawke products are tested, certified, inspectable and don’t generate waste during installation, avoiding the risk of fire due to flammable material and damage to auxiliary systems due to accumulation of waste.

No onsite modifications

This tolerant block enables a wide range of cable or pipe diameters to be accommodated by a compact range of tolerant blocks sizes. Hawke tolerant blocks have 5 sealing faces that are displaced by the sealing process.

This results in a tolerance of up to 4 mm for cable diameters, without any onsite modifications.

This acceptance range is sufficient to accommodate deviations found in cable tolerances.

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.

Thanks to this tolerance, each Hawke tolerant block seals a range of diameters between 3 and 4 mm.

Available in seven block sizes accommodating 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.

Tolerant block colour coding

Under certain site conditions, the general environment and lighting may make it difficult to select the correct blocks.

After installation the colour coding allows the inspector to clearly identify that the blocks have been correctly sized for the cable.

Without colour coding it is impossible to inspect that the system has been installed correctly.

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.

Unique compression system

Hawke Compression System

The Hawke compression system has 2 elements:

  •  End Packer
  •  Compression Plate.

Unique steel insert pins on both sides of the Hawke Transit Compression System ensure that the correct level of compression is applied to each installation, without the need for special knowledge or decisions on the part of the installer.

End Packer

The final element of the frame installation, this is inserted above the compression plate and the bolts tightened to seal the whole frame.

Compression plate

This goes on the top row of blocks, to distribute the pressure from the compression tool and compression system.

The solution for your industry

Where can Hawke Transit System be used?

Whatever a wall of bulkhead is penetrated by any type of cable or any kind of pipe or conduct, the occupants and integrity of the structure are exposed to risk from hazards such as:

Fire and smoke, water ingress, vermin, toxic gases and any external threats.
