With the OKA-G version, the side mesh apron should be run beneath the footplate of the levelling unit.

The fixing brackets with height adjustment screws contained in the packing set are roughly adjusted to the given screed height and are then applied to the trunking units.

Height adjustment

Fix the aligned trunking section to the raw screed using the fixing bracket.

Mounting the screed anchor

Adjusting the height adjustment supports

The height of previously aligned and fixed OKA trunking units can be adjusted using their fixing brackets. This mounting step should be carefully agreed with the screed layer. After height adjustment, do not place any loads on the trunking system.

Create trunking junction

The supplied screed anchors provide the joint between the screed and the trunking and are suspended in the aluminium side profile of the trunking units.

Before applying the screed, shorten any height-adjustment bolts protruding over the top edge of the trunking (at least 5 mm beneath screed height).

Create 90° angle

Create crossing

The OKAFB branching set allows trouble-free creation of junction trunking (T-junction). The mesh of the OKA-G can be processed using scissors or a knife and the metal floor base of the OKA-W can be processed using the single-handed angle industrial grinder.

End cap mounting

The OKAFB branching set allows trouble-free creation of 90° angles. The incoming trunking section is closed on the front side using a flushfloor end cover.

Crossings can be created in the same way as junctions, using the OKAFB branching set. The work corresponds to two opposing junctions.

There are standardised end caps available for the OKA-G and OKA-W trunking systems, which can be adjusted to the appropriate trunking height and which are simple to mount.

The screed should be installed directly after the OKA trunking system. The screed layer is obliged to line the side profiles well and to work the screed carefully and cleanly. Loads may not be placed on the trunking until the screed has hardened.

All the metallic parts of the trunking system must be included in the protective measure against indirect contact with parts carrying voltage and are therefore equipped with the appropriate connection options for the earth conductor clamp.
