Lined body solution for polished screeds
OBO cassettes for polished screeds
Seamless integration for the highest of design standards
Seamless floor areas such as Terrazzo or polished visible screed represent modern architecture, clean lines and lasting quality. With the cassette solutions from OBO Bettermann, access points to the electrical infrastructure can be integrated virtually invisibly into these premium floor concepts, without compromising on functionality or technology.
The OBO cassettes for polished screeds combine technological innovation with architectural freedom. They enable the seamless, aesthetic integration of electrical installations – ideal for modern construction projects with the highest of design standards.

The advantages of OBO cassettes at a glance:
Aesthetic & virtually invisible
- Seamless integration into terrazzo and visible screed surfaces
- No expansion joints, resulting in a harmonious overall appearance
- Minimally visible stainless steel edge – perfect for high-quality architecture
- Round and square designs

Sophisticated technology
- Decoupled system prevents transmission of footfall sound
- Floating cassette body adapts to screed movements
Maximum flexibility
- Adjustable systems for different structure heights
- Suitable for heated floors and different screed types
- Modular, for up to 12 Modul45® devices.

High level of planning security
- No expansion joint necessary
- Easy integration into sophisticated construction projects
- Complete system for efficient implementation
- 510 kg load-bearing capacity (point loads) → with a load capacity of 510 kg or higher, the square or round terrazzo lined body must be used.

Decoupled design for long-lasting floors
The innovative system mechanically separates the top and bottom parts of the cassette. The movements of the screed are absorbed without generating any tension. The result: Permanently dimensionally stable floors. Modern terrazzo floorings from well-known manufacturers, such as Ardex/Pandomo, complement the cassette solution perfectly thanks to the material’s high bending tensile strength.
Effective prevention of transmission of footfall sound
The decoupling of the system offers yet another benefit, as it effectively prevents the transmission of footfall sound.
By the way, even adjacent rooms without the cassette for jointless floors can be implemented completely noise-decoupled using the screed-covered duct system from OBO.
No joints, no compromises
Unlike classic floor boxes, the system does not require an expansion joint. The cassette and frame “float” in the screed, enabling a totally homogenous surface.


A villa that couldn’t be any closer to nature
The height-adjustable stainless steel cassettes from OBO Bettermann blend seamlessly into the flooring, offering a flexible power supply throughout the entire house – exactly where it’s needed.

Futurium Berlin
The “House of the Future” is now located between the Charité Hospital and the Office of the Federal Chancellor, in the centre of the government district. Underfloor systems from OBO Bettermann were installed, ensuring a flexible power supply.
High installation capacity
- Up to 12 Modul45® devices
- Alternatively, 9 standard devices (50 mm central plate)
- Flexible use for power, data and multimedia
Adaptable to any installation situation
- Infinitely adjustable
- Suitable for floor structure heights of 136 mm to 441 mm
- For use in: visible screeds, terrazzo flooring, heated stone floors
Typical applications for OBO cassettes:
Offices and administrative buildings
Flexible work environments require power and data connections that are concealed, but accessible at all times.
Exhibition and museum spaces
Changing installations and exhibits call for maximum flexibility, as well as a flawless appearance.
Event spaces
Temporary technology, stages or presentations are easy to connect, without visible infrastructure.
High-quality retail and hospitality concepts
Design-oriented sales floors or hotels benefit from concealed, integrated technology.
