RB-04Drill and fit the right fixing for your wallOn solid brick or block, drill a 6mm hole to 35-40mm depth, fit a wall plug, and use a screw long enough to grip fully inside it. On a timber stud, drill a pilot hole and drive a 4x40mm wood screw into the centre of the stud, not the edge. On a metal stud, never use a plastic plug or a wood screw, since a screw strips straight through 0.5mm steel; use a self-drilling metal-stud fixing or a toggle-type hollow-wall anchor rated for the bracket's pulling load. On dot-and-dab plasterboard, use a fixing long enough to pass through the board and the adhesive dabs, typically 75-90mm, so it grips the solid masonry behind, not just the board. On lath and plaster, fix through the lath into the masonry or joist behind with a longer screw, working slowly to avoid cracking the old plaster; if nothing solid lines up behind any of these, fit a timber noggin between the studs first rather than trust the board alone, since a roller blind gets pulled every time it's used.
