RB-09Fit the right fixing for your wall or frameIf you're fixing into a wooden or uPVC window frame, use the screws supplied with the bracket kit — no plug needed, just a pilot hole in timber. Into solid brick or block, drill with a 6-7mm masonry bit to the depth of the plug, insert a wall plug, and drive in the screw. For a stud wall above the window, work out what you have first: a stud detector or magnet tracking screw heads finds the studs, a hollow sound between them confirms plasterboard, and a small pilot hole tells you the rest — timber dust means a timber stud, fine grey swarf means a metal stud. Into a timber stud, use a wood screw straight into its centre; into a metal stud, use a self-drilling metal-stud fixing or toggle made for steel, never a plastic wall plug or ordinary wood screw, as both strip straight through 0.5mm steel. If the bracket falls on plasterboard between studs rather than on the stud itself, use a toggle or hollow-wall anchor rated for the blind's weight, not a light-duty picture hook fixing. On dot-and-dab plasterboard, use a fixing long enough to pass through the plasterboard and the adhesive dabs and bite into the masonry behind — check the cavity depth with a long thin drill bit first so you buy the right length.
