You need the following to assemble: Drilling machine with a 10 mm drill bit and screwdriver with a PH 2 bit for the screw. Important NOTE: Be careful not to drill into any electrical wires, ductwork, plumbing or other damagable components. If you have any questions on the locations of these wires or lines, please contact a professional electrician or plumber before drilling. The drywall anchor packaging includes three versions of grey add-on piece for the plug, a short, a middle and a long. When mounting a top track: Use the short add-on piece. When mounting wallband: Use the middle add-on piece. When fastening a hang standard or extension hang standard to the wall: Use the longer piece when fastening through the holes in the hang standard. Step 1: Start by drilling a hole with a small drill bit (2-3 mm). If you, for example, hit a wooden stud, don't use the drywall anchor in this position - attach with a wood screw. If you hit a hollow part of the wall, enlarge the hole with a 10 mm drill bit. Step 2: Add the adequate add-on piece into the plastic plug and push the plastic plug into the hole. Step 3: Mount with the screw using a PH 2 bit.
