AB-04Drill and fit the right fixing for your wallOn lath and plaster, drill a 3mm pilot hole first — if you hit a solid timber stud or joist behind the laths, drive a wood screw into its centre. If there's no stud behind your marks, use a spring-toggle or spiral lath fixing rated for the rack's weight, which spreads the load across the laths instead of relying on crumbly plaster alone. On solid brick or block, drill with a 6mm masonry bit to 40mm depth, fit a matching wall plug, then screw in. On plasterboard over timber studs, screw straight into the centre of the stud; between studs, use a plasterboard toggle rated for the rack's weight. On plasterboard over metal studs, use a self-drilling metal-stud fixing or hollow-wall toggle — never a plain plastic plug or wood screw, as these strip straight through 0.5mm steel. On dot-and-dab plasterboard, use a fixing long enough to pass through the plasterboard and adhesive dabs and grip the solid masonry behind, usually 60-75mm.
