Screw-On Drywall Outside Corner Guard
A 150 mm tall L-shaped guard that screws over a 90° outside drywall corner. It stops vacuums, strollers and furniture from crushing the corner bead. Each flange is 32 mm wide and 3 mm thick, with a 6 mm bullnose at the corner and a 2 mm relief groove so it sits flat over a raised metal bead. It has five staggered 4.5 mm countersunk holes for #6 (3.5 mm) or #8 (4.2 mm) wood screws, or for screws in plastic drywall anchors.
Drywall Hole Patch Backer Bridge
A 140 x 36 x 5 mm backer plate for patching a hole in 1/2 in (12.7 mm) drywall. Tilt it in through any hole about 40–95 mm across, such as a doorknob punch-through or an old box cut-out. Pull the finger handle to hold it tight against the back of the wall, then drive #6 drywall screws through the wall into the 2.6 mm pilot holes 52–64 mm either side of centre. Screw your plug patch into the two centre holes. The handle has a 2.4 mm neck at the plate face, so it snaps off almost flush when you're done.
