AB-04Fix the radiator guard or cover to the wallBefore drilling, use your detector but still treat the wall as live: cables and pipes can run almost anywhere, and detectors miss deep cables, armoured cable and anything behind metal-backed plasterboard. Radiator pipes often run up the wall right beside the radiator, so keep fixings well clear of them, and know where your stopcock is in case you hit one. Into a timber stud, use a 4mm or 5mm wood screw driven into the centre of the upright. Into a metal stud, use a self-drilling metal-stud fixing or a hollow-wall toggle - never a plastic wall plug or an ordinary wood screw, which strips straight through 0.5mm steel. Fixing into plasterboard between studs, use a toggle or hollow-wall anchor rated for the guard's weight. Into solid brick or block, drill an 8mm hole to the plug's depth and use a wall plug with a 40mm screw. Through dot-and-dab plasterboard, use a fixing long enough to pass through the board and dabs and bite at least 30mm into the masonry behind. Once fixed, check the guard still lets heat escape - never box a radiator in tightly, and keep the top and any vents clear.
