Features & Benefits


High Crush Strength

MULTIduct does not require any concrete or specialist surround due to its high strength and robust nature – requiring shallower burial depths and possessing greater crush resistance.

Quick Assembly

With Secure One Click Connection System

The MULTIduct cable Protection System offers a unique ‘plush fit system’ that is fast and easy to install. During cable pulling, the unique push-fit connection eliminates any disengagement of the units once installed.

Durable Cable Protection

Less susceptible to drop related damages, MULTIduct offers a durable and lightweight unit that can be easily transported and moved on site.The cable protection unit also incorporates large radius corners to stop rodents gaining access to the cabling inside of the duct.

MUTIduct – A Multiple Duct Combination

Cubs MULTIduct combines multiple cable ducts that would traditionally, have been separated. This results in the need for a reduced excavation resulting in narrower and shallower trenches. there is no graded back fill between ducts and time is reduced during installation.


Weighing under 20kg MULTIduct™ offers significant health and safety advantages. MULTIduct™ is suitable for a single person lift and install, enabling compliance with manual handling regulations. Being lightweight and easy to deploy results in considerable project time and cost savings.

Buried Cable Routes

MULTIduct can be used in conjunction with other Cubis products, such as the STAKKAbox Access Chamber Systems, to create a more secure ducting system than surface routes. This can prevent issues with theft and vandalism to cables.

Straight And Flat With Added Flexibility

MULTIduct™ allows for 2° of flexibility within its connection. This results in the creation of a natural bend that can follow the curvature of a track, road or tunnel installation. The straight lay flat feature removes the need for spaces and eliminates any twisting issues during the installation unlike traditional ducting systems.

Square Duct Space

Unique smooth internal walls for easier cable pulling and no sharp edges for cable damage. Less surface contact with cables makes it easier to pull / blow during cable installation. The shape of the MULTIduct™ units increase capacity over traditional cable ducts.
