TR-07Fixing for other wall types, if that's what you've gotOn solid brick or block, drill 40-50mm deep with a 6-7mm masonry bit, fit a standard Rawlplug, then screw in. On timber studs, find the centre of the stud and drive a 40-50mm wood screw straight in — no plug needed. On metal studs, never use a plain plug or wood screw, as it strips straight through 0.5mm steel; use a self-drilling metal-stud fixing or a toggle-type hollow-wall anchor rated for the weight, and if the ring will be pulled or leant on, fix into a timber noggin or pattress instead. On lath and plaster, drill slowly to avoid cracking the old lime plaster, and use a spring toggle that spans the laths, or locate a timber upright behind and screw into that.
