CB-05Choose the right fixing for your wall typeFor dot-and-dab plasterboard (the usual case for this job), you need a long fixing that passes through the plasterboard, crosses the air gap behind it, and grips into the solid masonry behind — a standard wall plug is too short and will only hold the plasterboard, not the wall. For solid brick or block with no dot-and-dab, use a standard wall plug and screw sized to the load. For a timber stud wall, use a wood screw driven into the centre of the stud. For a metal stud wall, use a self-drilling metal-stud fixing or a toggle-type hollow-wall anchor made for metal studs — never a plain wall plug or ordinary wood screw, as both strip straight through 0.5mm steel. A metal stud alone will not hold a fully loaded cabinet safely; if that's what you have, fit a timber noggin between the studs first or fix through to the masonry behind. For lath and plaster, standard wall plugs will crumble the lath — use a long fixing that reaches past the laths into solid masonry, or a specialist lath-and-plaster fixing.
