)
NOTE
The tension cable must be perpendicular to the top
rail.
The lower edge of the tension cable brackets must
be approx. 40 mm below the lower edge of the
bottom rail when the external venetian blind is fully
extended.

Lower the external venetian blind completely.
Align the tension cable perpendicular to the top rail
and mark its position on the substructure.
Pencil the bottom edge of the bottom rail (plus
40 mm) onto the mounting substructure.
Hold the tension cable
bracket against the mar-
king, properly aligned
both vertically and hori-
zontally.
Transfer the fixing temp-
late of the tension cable
bracket onto the
mounting substructure.

Fixation suggestions for tension cable brackets
(selected mounting substructures)
Attach the tension cable
bracket to the substruc-
ture with suitable fixing
material.
Aligning the tension cable
Check the tension cable
brackets to ensure they
have the same height
(B) and are parallel
(X1 = X2 ± 1 mm).
Measure diagonals "D1"
and "D2". If D1 = D2,
the tension cables are
parallel and at right
angles.
