Explanation of Symbols
These symbols indicate the profile series in which
a connecting element or accessory component can
be used. Connecting elements and accessory components
without a series symbol can be used in all
profile series. An assortment of connector pieces is
available for the round tube profiles D28.
These symbols indicate the slot width of the profile
or profile series in millimetres.
The cross reference symbol with a corresponding
page number refers you to complimentary products
or information that can be found elsewhere in the

These symbols indicate the screws to be
used (thread x length in mm). If screws
compliant with a specific standard are
required, this is also indicated.
Items labelled with the ESD symbol have a discharging
or conductive design and are therefore suitable
for used in ESD-sensitive areas or for creating ESD
protection zones. These products guarantee a resistance
to earth from the contact point of < 1011
ohms. Common items include nuts/T-nuts, which
have a conductive design with < 102 ohms.
This symbol identifies select profiles that are also
available in a curved variant. The number indicates
the minimum possible inner radius in millimetres.
The profiles can only be bent along the narrow side
of the profile (horizontal bending axis).
