DANGER!
Danger to life from incorrectly installed and threaded
hardware
components!
Incorrect installation and threading of hardware components can
result in dangerous circumstances and cause severe accidents,
even including death.
Therefore:
– For installation and especially for threaded components, observe
the
product-specific documentation of the hardware manu-
facturer,
the information from the profile manufacturer, and all
contents of the TBDK directive of the Gütegemeinschaft
Schlösser und Beschläge.
For fixing the hardware components, Ø 3.9–4.2 x ... zinc plated and
passivated
steel fenestration screws are to be used. In the case of special
climatic conditions, use fenestration screws with additional sealing.
The window fabricator must ensure adequate fixing of the hardware
components
, consulting the screw manufacturer if necessary. When fixing
security relevant, supportive hardware components such as stay
bearings
and pivot rests, the tearing-forces vertical to the sash plane
surface
must be reached in accordance with the following table (the
tractive
-force values depend on the sash weights from the TBDK).
Sash weight in kg Tractive force in N

60 1650
70 1900
80 2200
90 2450
100 2710
110 3000
120 3250
130 3500

150 4200
200 5500
1) acceptable tolerance -10%.
The stated values refer to the stay bearing. These are also valid for the pivot
rest if the fixing is carried out in the same manner as with the stay bearing.
On corrosive timber (i.e. afzelia, oak etc.), the hardware’s routed-areas are
to be treated with a protective coating before installing the hardware in
order
to protect the hardware.
Do not use any acid cross-linked sealing compounds that could lead to
corrosion
of the hardware components.
The glazing spacer-block regulations for the glazing method are to be
adhered
to.
