You now need to mark
the frame to drill the 2
holes, use a 2.5mm drill
bit for this.
Offer the opener up to
the frame with the plates
and washers and slide
the louvre arm into
position. This now gives
you the correct location
for the opener (diagram
60). Once you have
marked the frame
remove the opener to
drill the holes.
Now fix the opener to
the frame using the 2
plates and 2 washers
(diagram 61). You
should have either
19mm or 25mm screws

greenhouse frame for
this.
Once fixed in place
attached the louvre arm
to the opener and hold
in place with the plastic
pop-on cap (diagram 62).
