MCT system installer

Inspectionability; a basic aspect when choosing a sealing system for cables and pipes

Hawke Transit System makes it easy to inspect MCT systems by color-coding their blocks

It is common to find cable entry installations in spaces that are difficult to access or with little lighting, which in many cases make it extremely difficult not only for the installation but also for the subsequent inspection of that installation or its modification if necessary. For this reason it is vitally important that the chosen sealing system facilitates its inspectability.


Faced with an extreme situation, an installation error can have terrible consequences for the occupants of the space in question and for the entire construction. With this in mind, Hawke Transit System developed a color-coding system that made it easier for the installer to verify that the installation had been done correctly.

In this system each individual plug has a color-coded face, which ensures that each size and pair of halves of each block always correctly match the diameter of the cable.

This color coding allows the inspector to identify without the possibility of error that the blocks have been correctly dimensioned for each wire size.

As we can see in the image, an installation with all the plugs of the same color sealing different cable diameters, makes it very difficult to inspect and can easily generate installation errors. While the use of color-coded plugs greatly facilitates inspection and avoids installation errors.

After different tests, at Hawke Transit System we are clear that the use of color-coded blocks limits installation errors to practically zero and facilitates the installer’s work, saving him a lot of time and effort.
