AS panel component - Häfele Cat. No.: 262.50.359 and 262.50.358
AS frame component - Häfele Cat. No.: 262.50.368 and 262.50.377
ASR frame component - Häfele Cat. No.: 262.50.390 and 262.50.39
Keku fittings are made of polycarbonate (PC).The production of the fittings is subjected to continuous quality control. Individual fitting components resist tension and compression forces of 300 N in all directions.
The maximum load capacity of a pair of fittings in the following applications is
20 kg. These values are not valid for the coupling effect of push-in fittings AS
and ASR.
These push-in fittings are not for hanging loads e.g. ceiling tiles.
At least four fittings are required when hanging a rectangular panel. The spacing depends on the panel thickness as well as the arrangement of attachment points and should not exceed 600 mm. For uniform distribution of the load, the fittings must be positioned precisely.
Regarding the number of different applications, we recommend that the worker performs a trial assembly.
Load carrying plastic fittings should not be treated with chemical solutions or aggressive greases. The processing parameters contained in the Häfele catalogue must be observed.
According to the material testing institutes and their uniform statement, fittings generally are assessed with regard to fire resistance in compliance with DIN 4102 only after installation and in combination with a structural component.
This means that Keku fittings are not tested individually before installation and are not considered as material such as sub-construction or panel and finishing material, which are classified into fire resistance categories A1, A2 (not flammable) or B1 (hardly flammable), B2 (standard flammable) or B3 (easily flammable).
Keku fittings are made of polycarbonate (PC).
According to tests of the Underwrites`s Laboratories (UL), USA, this base material is classified,depending on the type, into the fire resistance categories V-0, V-1 or V-2 (see separate note. We use polycarbonate that complies with the standard type 2600/2800 – V1, comparatively B1.
