Cutting lengths (Figure 4):
Figure 4a, Standard Cutting Lengths of Tubes and Fabric
Top Tube
=
Distance between centre of drilled holes -10mm (-0.010m)
Screen and Flap =
Distance between centre of drilled holes
-90mm (-0.090m)
(80mm
shorter
than
top
tube)
Bottom Tube
=
Distance between centre of drilled holes
+10mm (0.010m)
(20mm longer than top tube)
NOTE: Cutting details are for standard installation where there
are no constraints on fixing the top brackets or J brackets. It is
possible to reduce the distance between top brackets if there
are space constraints (Figure 4b). This configuration however
results in a 5mm gap between the fabric and the door opening
