PR-04Choose the right fixing for your wallOn solid brick or block, drill 6-8mm holes to a 40-50mm depth, fit a plastic wall plug, and use a wood screw. On plasterboard over TIMBER studs, drive a wood screw straight into the centre of the stud with no plug needed. On plasterboard over METAL studs, use a self-drilling metal-stud screw or a self-drilling hollow-wall anchor rated for metal studs — never a plain wall plug and never an ordinary wood screw, as it will strip straight through 0.5mm steel. Where a hole falls between metal studs with no stud behind it, use a metal-rated toggle or spring fixing sized for the rack's loaded weight, and if a fixing point is over dot-and-dab plasterboard, choose a fixing long enough to pass through the board, the adhesive dabs, and bite into the masonry behind; lath and plaster needs a similar long fixing through to a solid lath or the wall behind, as the plaster itself won't hold weight.
