GW-05Choose the right fixing for what you foundOn dot-and-dab, light frames under about 2kg can use a self-drilling plasterboard anchor, ideally landing in a solid dab rather than a gap. Heavier or larger frames need a longer 60-75mm fixing that passes through the plasterboard and dab into the masonry behind, with a wall plug and drill bit matched to it. On a timber stud, drive a wood screw straight into the centre of the stud - no plug needed. On a metal stud, use a self-drilling metal-stud fixing or a toggle-type hollow-wall anchor made for steel track; never use a plain plastic wall plug or an ordinary wood screw, as it strips straight through 0.5mm steel. A metal stud won't hold anything heavy, so for a large or weighty frame fit a timber noggin between the studs first, or fix through to the masonry behind, rather than trusting the stud alone. If the fixing point falls on plasterboard between studs, use a toggle or hollow-wall anchor rated for the frame's weight. In solid brick or block, drill with a masonry bit matched to the plug, insert the plug, and drive in a screw. On lath and plaster, avoid narrow laths where possible and use a longer fixing that grips through into the void behind, or a lath-and-plaster-specific anchor, since ordinary plugs often just crumble the old plaster.
