AB-05Use the right fixing if the rail continues onto a different wall typeIf part of your rail run lands on a timber stud, use an ordinary wood screw driven into the centre of the stud — no plug needed. On a metal stud, use a proper self-drilling metal-stud fixing or toggle-type hollow-wall anchor; never use a plain plastic wall plug or a wood screw, as both strip straight through 0.5mm steel. If a fixing point falls on plasterboard between studs, use a toggle or hollow-wall anchor rated for the weight of the rail and pictures, not just a picture hook. On dot-and-dab plasterboard, use a fixing long enough to pass through the void behind and grip the masonry, not just the plasterboard skin. On lath and plaster, find a timber lath or noggin first, then use a fine screw with a pilot hole to avoid cracking the old plaster.
