Mounting fittings

Vertical and horizontal changes of direction are created with fittings.
Normally, fittings of up to 300 mm width are mounted on cable trays with
the WKV angle connectors supplied. Fittings with a width of 400 mm or
more have a connector perforation and are mounted on cable trays with
FRS M6 truss-head bolts and combination nuts.

Supporting a fitting

Fittings must always be supported by the support system. The mounting
of the different support systems is shown in special mounting instruc-
tions, see "1.6 Applicable documents" on page 6.
Risk of the support system falling!
If fittings are not supported, cable loads can become too heavy, desta-

bilising the entire support system. There is a risk of the support system
falling. Depending on their width, support the fittings with an additional
support element.
Fitting support up to 300 mm width
Up to a width of 300 mm, mounting of one support of the cable trays at a
distance of 250–300 mm from the edge of the fitting is sufficient.
