MULTIduct™
The undisputed #1 multiple duct system on the market.
MULTIduct™ from Cubis Systems replaces traditional duct banks with a single structural unit.
On-site teams benefit from multiple ducts combined, simple assembly, and components under 20kg for single-person handling.
The solution holds numerous global approvals and has been installed in various applications and environments across the world.
MULTIduct™ is readily available for your projects in 4-way, 6-way, 9-way, and 4-way XL configurations - get in touch to discuss.

Key product highlights
Narrower, shallow trenches
MULTIduct™ can be buried much shallower than conventional duct. The product offers high crush strength and robust composition that reduces traditional breakage risk.
Safely manually handled
Weighing under 20kg, MULTIduct™ offers significant health and safety advantages. It's suitable for single person lift and installation, in compliance with manual handling regulations.
No specialist surround
Requires no concrete or specialist surround due to its high strength. Excavated material can be reused during re-installation — reducing time, cost and heavy plant.
Buried cable routes
In conjunction with our STAKKAbox™ access chamber systems, MULTIduct™ offers a more secure ducting system than surface routes. This can prevent issues with theft and vandalism to cables.
Lightweight yet durable
MULTIduct™ is a durable, lightweight unit that is easy to transport on site, resists drop-related damage, and features large-radius corners to help prevent rodent access to cabling.
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.
Multiple ducts combined
Combines multiple (traditionally separated) cable ducts into one unit — making for an easier and more economical project with less civils work and less effort, in less time.
Lay flat straightness
MULTIduct™ lays straighter and flatter than traditional ducting. This lay-flat, run-straight design removes the need for spaces and eliminates any twisting issues during the installation.
MULTIduct™ vs traditional ducting
Quick one-click assembly
MULTIduct™ units are quickly and easily assembled by connecting nominal one (1) metre-long sections together via a unique 'push-fit' system. During cable pulling, this unique push-fit connection eliminates any disengagement of the units once installed.

Seamless system integration
MULTIduct™ has been designed to offer seamless integration with the Cubis Systems range of pit access products such as STAKKAbox™ ULTIMA Connect.
In turn, this enables enhanced cable management and access.
- MULTIduct™ can be easily integrated into the desired STAKKAbox™ access chamber on site - using readily available tools
- Alternatively, for even faster installation, access chamber entry points can be pre-fitted to our STAKKAbox™ chambers at production
- We can also fit a socket or spigot end to make connection even simpler, and deliver to site as a single unit
- If the exact duct entry positions are unknown at the time of order, we can fit a flexible sliding backfill barrier
- This barrier allows for up to 150mm vertical alteration, enabling the MULTIduct™ entry position to be customised on-site
- Design support is also available throughout to help optimise product selection and plans

MULTIduct™ options and accessories
MULTIduct™ comes with a full range of accessories designed to handle your real-world installation scenarios, including tight turns, elevations, adjustable height on site, natural curvature and other obstacles. Every component is engineered to work together to give you a complete cable management system designed for flexibility, performance, and ease of installation.
Sockets and spigots
- Use to join matching lengths of MULTIduct™
- Female to female (socket to socket) and male to male (spigot to spigot)
End caps
- Use to terminate male and female (socket and spigot) duct entry points
- Order pre-fitted for easier installation
Duct plugs
- Square and corner plugs you can use to seal duct compartments
- Protect against sand, backfill, and rodents
Mitre joints
- MULTIduct™ will allow up to 2° of movement at each joint
- Use mitres to create sharper curvature angles
Duct adaptors
- Single-way adaptors to integrate easily with traditional ducting
- Use to adapt and split off into individual conduit runs
Fast fact: our recent MULTIduct™ design support helped a client save £235k on ducting and installation costs. That represented a 48% cost reduction – driven by optimising MULTIduct™ specification at the design stage.
Want specification support before you order?
For customers working with MULTIduct™ products in their projects, we can offer you a focused design session. Here, our specification engineers can work with your drawings, constraints, and project outcomes to help you:
- Optimise product selection and plans (picking the right solution, applied the right way)
- Reduce materials and embodied carbon through smarter configuration
- Improve buildability and accelerate installation planning
- Increase design confidence with validated data and CAD/BIM-ready outputs
You’ll leave with clearer direction, fewer unknowns, and a design that’s easier to deliver on site.
