Fit an alcove wardrobe rail to a metal stud wall

Fit a sturdy wardrobe rail across an alcove, working out what's behind the wall before you drill and fix it securely.

AW-01Plan the rail height and clear the alcoveEmpty the alcove and take down anything already fixed there. Decide the rail height — 1600-1800mm from the floor suits full-length hanging, or 900-1000mm if you're adding a shelf above. Mark a level line across the back wall with a spirit level, then carry the same height mark onto both side walls. Measure the alcove width at rail height on both sides, since alcoves are rarely perfectly square.

AW-02Work out what each side wall is made ofThe rail fixes into two side walls, and they're often built differently even in the same room. Tap the wall at rail height — a solid, dead sound usually means brick or block, a hollow sound means stud wall or dot-and-dab plasterboard. Run a magnet along the marked line: it grips onto a metal stud track through the plasterboard, but on a timber stud it only sticks to screw heads. Drill a small 3mm pilot hole at your fixing point — pale dust means plasterboard or masonry, timber shavings mean a wood stud, bright metal swarf means a steel stud.

AW-03Check for cables and pipes before you drillCables and pipes can run almost anywhere in a wall, and a metal stud track can throw off a cheap detector. Use a cable and pipe detector along your whole fixing line, but still treat every hole as if something could be behind it. Find your stopcock (usually under the kitchen sink) and check it turns before you start, so you can shut off water fast if you hit a pipe. If you've any doubt, isolate the relevant circuit at the consumer unit before drilling, and turn off the water at the stopcock before cutting into anything that could carry it.

AW-04Fit a timber noggin if you have a metal stud wallA wardrobe rail gets loaded and pulled on constantly, and a metal stud on its own will not hold that — the fixing works loose or the plasterboard tears. Cut a piece of 50x50mm timber to span between two metal studs (usually 600mm apart), open a small section of plasterboard, and fix the timber flat across the studs using 25mm self-drilling metal stud screws. If you'd rather not open the plasterboard, screw an 18mm plywood pattress across at least two studs instead, or fix a batten straight through to any masonry directly behind the stud frame.

AW-05Fix the rail brackets to each wallMetal stud with a noggin fitted: drill a 2mm pilot hole and drive a 4mm x 40mm wood screw into the centre of the timber. Timber stud: screw straight into the centre of the stud with the same size screw, no plug needed. Solid brick or block: drill an 8mm hole 50mm deep, insert a wall plug, and drive in a 5mm x 60mm screw. Dot-and-dab plasterboard: use a fixing long enough to pass through the board and adhesive dabs into the masonry behind — typically a 75mm masonry screw with a matching plug — never a plasterboard toggle alone for a load-bearing bracket. Lath and plaster: find a solid lath with a bradawl first, since a gap between laths will crumble the plaster, then fix as for a timber stud.

AW-06Level up and fit the railHold a spirit level across both brackets before final tightening, and shim one bracket slightly if the alcove isn't quite square. Clip or screw the rail into the brackets following the manufacturer's fittings. Give the rail a firm tug test at both ends to check the fixings hold before loading it up.

AW-07Load test and tidy upHang some heavy items on the rail and check after a few days of normal use that nothing flexes or creaks at the brackets. Patch any plasterboard you opened to fit a noggin with an offcut, filler, and a light sand once dry. Vacuum up dust and swarf from drilling and dispose of offcuts.
