SP-06Fix the top rail and skirting capFor a TIMBER stud wall, screw through the rail into the centre of each stud using 50-60mm wood screws, driving a pilot hole first. For a METAL stud wall, use self-drilling metal-stud screws designed for 0.5mm steel track - never a wood screw, which strips straight through, and never a plain plastic wall plug. For SOLID BRICK OR BLOCK, drill 7mm holes to 45mm depth, insert red wall plugs and fix with 50mm screws. For DOT-AND-DAB plasterboard, use a fixing long enough to pass through the plasterboard and dab (often 75-90mm) into the masonry behind, or use a suitable dot-and-dab-rated frame fixing. For LATH AND PLASTER, screw into the timber laths where you find them solid, or fix into the timber studs behind if accessible, since the plaster itself will crumble under load.
