vided push rod components can be combined
as needed (Fig. 12).
If the length of the push rod is not sufficient, it
can be adjusted via the extension rod (Fig.

ommend the use of a sectional door angle
(Fig. 12c). Then the provided door bracket
(Fig. 12b) has to be attached to the push rod.
For the assembly use the provided screws,
washers and nuts, and tighten them firmly.
