Key features & benefits
Flexible applications
The system is easy to adapt on-site using standard tools. Installers can overbuild existing networks, introduce new duct entries, and fine-tune the top section for hassle-free project flexibility.
Rapid installation
STAKKAbox™ chambers are significantly faster to install than conventional alternatives. Complete installations typically take less than one hour — resulting in reduced costs for the installer.
Sectional design
STAKKAbox™ Utility is built in easy-to-handle 150mm sections, allowing installers to quickly achieve the required depth without the need for lifting equipment.
Light but strong
Twin-wall construction keeps each section lightweight for manual handling. Each access chamber has vertical and horizontal ribs, resulting in exceptional strength in vertical and sidewall loading.
Reduced installation costs
No need for specialist backfills means faster installs and lower costs. This makes STAKKAbox™ Utility a smart, efficient choice for any underground utility project.
Made in Britain
Cubis Systems is a proud British manufacturer. So, as well as the inherent sustainability of using the recycled and recyclable STAKKAbox™ Utility, you also gain a greener supply chain.
Minimal drilling
The product's integrated duct knockouts and predefined drill points allow contractors to complete installs as quickly, easily, and inexpensively as possible.
A single product line
Our patent-pending solid ring structure means that STAKKAbox™ Utility isn't made up of component parts — reducing ordering, handling, training, inventory, and installation needs.
