Keku® FittingEH and EHS suspension fitting,AS and ASR slide-on fitting,AD 15 and AD 30 double partition fitting

The fire class of the components depends on the materials of the processed panelling and cladding

materials. The Keku® R aluminium room system is regarded as not flammable. Fire class A

According to a uniform statement from the material testing institutes, fittings must generally only be assessed with regard to fire resistance in accordance with DIN 4102 in the installed condition and in connection with a component.

This means that the Keku® fittings are also not tested as individual components in the noninstalled condition and are not regarded as materials such as the subconstruction or the panelling and finishing material, which is evaluated in accordance with fire protection class A1, A2 (not flammable) or B1 (hardly inflammable), B2(normally inflammable) or B3 (easily flammable).

Please note the processing instructions and technical values. We will gladly provide load tables and data sheets for you.

The processing of the Keku® system requires conscientious, skilful handling. Trial assemblies are recommended for special loads and unusual designs. Persons unfamiliar with the trade and maintenance personnel must be provided with instruction about the handling of the inspection panels.

Keku® suspension fittings EH and EHS

Panel component Keku® EH - Art.-Nr.: 262.49.356 und 262.49.357,

Frame component Keku® EH - Art.-Nr.: 262.49.360, 262.49.365 und 262.49.366,

Frame component Keku® EHS - Art.-Nr.: 262.49.367 und 262.49.368

Keku fittings are made of polycarbonate (PC).

The production of the fittings is subjected to continuous quality control.

The Keku fittings resist short-term tensions and compression forces of 300N and then have to return

to the starting position.

The maximum load capacity of a pair of fittings in the following applications is:

• For vertical suspension in e.g. wall panels 20 kg

• For horizontal application, lying e.g. pedestal panels 30 kg

• For horizontal applications, hanging e.g. ceiling panels 8 kg

At least 4 pairs of 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.

Frame component Keku® ASR - Häfele Art.-No.: 262.50.390 and 262.50.39



The Keku fittings resist short-term tensions and compression forces of 300N and then have to return

to the starting position.

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 4 pairs of 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.

Material properties:

Keku® R room system and Keku® hardware system

The Keku fittings are sold since 1982 by the company Häfele GmbH & Co.KG in millions.

Polycarbonate combines many good properties of metals, glass and plastics such as stiffness, impact resistance, dimensional stability, good insulating properties and good heat resistance.

It is considered as a high-quality engineering plastic with high strength and hardness with good toughness. Its good electrical insulating properties are almost independent of ambient temperature and humidity. The high dimensional stability in heat and the low thermal expansion coefficient show good thermal behavior.

Polycarbonate is flame retardant but burns bright, sooty and self-extinguishing. The polycarbonate (PC) we use is the ideal material for the functions of the Keku-R hardware system.

Information required by the Material Examination Offices Berlin and DortmundThe metallic parts of the substructure can comply with DIN 4102-4 of building material class Al(non-combustible).The fittings made of polycarbonate require no proof of fire behavior if the following boundary conditions are met:Mass less than or equal to 50g and dimensions less than or equal to 50mm x 50mm.The contribution to the incipient fire and transmission can then be neglected. Separate evidence of the fire behavior must be provided for the board materials used.Either by general building authority test certificates (ABP) or by general building inspectorate approvals (ABZ) or by CE marking.Due to the purpose of use there are currently for the metalComponents of the room system no requirement of a building inspection approval.

The coupling effect depends on many different parameters. Plate material, plate thickness, tightening forces of the fittings, accuracy of the Keku positions, etc.

Self-tests are indispensable for determining the locking effect.

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.

Given the multitude of possible applications, we recommend to the fabricator, for special requirements, make trial fittings.

The production of fittings is subject to constant quality control.Various special screws are available for attaching the fittings to the Keku®R system.

The maximum load capacity of a pair of fittings in the following applications is:

• For vertical suspension in e.g. wall panels 20 Kg• For horizontal application, lying e.g. pedestal panels 30 Kg• For horizontal applications, hanging e.g. ceiling panels 8 Kg

Quality assurance

The authenticity of our fittings, which are protected by trade mark, can be verified by the following markings:Cacity, material, year of manufacture, month of manufacture and make

1: Cavity2: Material 3: Year4: Month5: Make

A certified quality assurance system monitors all manufacturing processes.

The basic material for the keku fittings is a polycarbonate (PC)

A structural FEM calculation confirms that the assemblies have been made using the materialthat we have specified.

The Keku fittings and the Keku R room system fulfil all requirements of the latest version of theREACH and RoHs legislation.

The legal SCCP limit - short chain chlorinated paraffins - is complied with.

The Keku fittings are made in Germany.

The fire class of the components depends on the materials of the processed panelling and cladding

materials.The Keku® R aluminium room system is regarded as not flammable. Fire class According to a

uniform statement from the material testing institutes, fittings must generally only be assessed with

regard to fire resistance in accordance with DIN 4102 in the installed condition and in connection with

a component.This means that the Keku® fittings are also not tested as individual components in the

non-installed condition and are not regarded as materials such as the sub-construction or the panelling

and finishing material, which is evaluated in accordance with fire protection class A1, A2 (not

flammable) or B1 (hardly inflammable), B2 (normally inflammable) or B3 (easily flammable).

The processing of the Keku® system requires conscientious, skilful handling. Trial assemblies are recommended for

special loads and unusual designs. Persons unfamiliar with the trade and maintenance personnel must be provided

with instruction about the handling of the inspection panels.. At least 4 pairs of 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 basic material for

the Keku® suspension, slide-on and double partition fittings is a polycarbonate (PC). A certified quality assurance

system monitors all manufacturing processes. A structural FEM calculation confirms that the assemblies have been
