How's best to fit them on plasterboard walls? No studs found. Underneath a window. Double panel. 1600 x 300

cut the plasterboard out behind where the brackets are, so cut out 2 bits with a padsaw, say 250 long (300mm rad) by 100mm wide. now cut 2 bits of 18mm ply, 250mm long by 200mm wide. Slide the ply into the hole in the wall at an angle (be careful not to drop it inside the wall, you need to put a screw in the middle of the ply with the head sticking out to give yourself something to hold onto)

Now the ply is behind the wall, centre it up in the hole so it overlaps each side evenly 50mm then screw though the edges (25mm in) of the left and right side of the plasterboard and into the ply which will pinch it all together. Now replace the PB you cut out earlier and screw it into the ply.

above is the best way of doing it for slighty bigger rads IMO, saves cutting the wall out for studs, small rads I use the brolly type plasterboard fixings, or spring toggles (I prefer spring toggles for strength over the brolly ones.
 
What does the setting tool do and how do you use it?

It expands the anchor, you put the anchor in the wall and the tool basically pulls the screw head away from the wall which inturn opens the anchor up behind the wall like an umbrella

you load the fixing into the setting tool and it has a Rachel action on the trigger so it flares out the fitting by pulling the screw head if that makes sense. It's well handy for when your using them quite a bit, tightening with a drill/driver you can pull the fixing through the wall, you can't with the setting tool.
