Depending on the available space and your own preference, you can fit the roller blind in front of the window in different ways:
Check that there are no protruding parts that could obstruct the roller blind when you raise or lower it – for example a window handle that sticks out too far. In that case you can consider hanging the blind so that it rolls and unrolls from the front of the roller, instead of from the back.
If you want to hang the blind inside the window frame, simply enter the exact width of the inside of the window frame refer to Pic. 7 (at bottom of page)
Decide whether you want to fit the chain of the roller blind on the left or right side.
Decide on the position of the first bracket and mark the drilling holes. If you’re fitting the bracket to the window frame, first pre-drill the holes with a thin wood drill bit (2.5 mm). Or if you’re fitting the blind to the wall, use a 6 mm masonry drill bit together with wall plugs of the same size. Then fit the first bracket and lightly tighten the screws. Using a long strip of wood, adjust the roller with a spirit level so it is horizontal. Then mark the drilling holes for the second bracket.
First insert the roller into the bracket with the chain mechanism, and then into the other bracket.
