AW-05Fix the end brackets to the wallInto a timber stud, drill a 3mm pilot hole into the centre of the stud and drive in a 40mm No.8 wood screw. Into a metal stud, never use a wood screw or plastic plug, as they strip straight through 0.5mm steel; use a self-drilling metal-stud screw for light loads, or a toggle-type hollow-wall anchor rated for the bracket weight. Into solid brick or block, drill with a 6mm masonry bit to 45mm deep, insert a wall plug, and drive in a 50mm screw. Through dot-and-dab plasterboard, use a long fixing (60-75mm) that passes through the board and adhesive dabs into the solid masonry behind, and into lath and plaster locate solid timber behind the laths where possible, or use a proper plasterboard-rated toggle fixing between laths, drilling gently as old plaster is brittle.
