Underfloor systems

Delivery as a ready-to-mount

The benefits of the OKA system can be seen directly when they are delivered to the construction site. The ready-for-mounting cable units are screwed together and their stable construction can withstand all the requirements of the construction site. The practical accessories simplify and accelerate the mounting of the system.


The OKA trunking has a length of 2,400 mm and is available in the widths 200 mm, 300 mm, 400 mm, 500 mm and 600 mm.

Height-adjustment units with equipotential bonding

The supplied height-adjustment units allow simple height-adjustment, fastening and conductive connection of the OKA trunking. The height-adjustment takes place in two stages: Firstly, the height-adjustment units are roughly pre-adjusted to the given screed height using the integrated quick height-adjustment function and applied to the trunking units. In the second step, after fastening, the fine adjustment to the top edge of the screed is carried out using a screwdriver.
