You need the following to assemble: Screwdriver/drilling machine, metal saw (if adding top tracks and/or adjusting top track widths), leveller. Before you start: Make sure you have chosen the right screw/plug for your wall type.The recommendation, when mounting the top track, is to use Elfa hardware. We recommended that a screw should be placed in every hole, for maximum saftey.  The screw holes in the top track are shaped oval, in order to increase the probability to find studs to mount in. 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. Step 1 (Mounting the top track): Place the top track at the desired height and mark one hole in the middle. Begin drilling the marked hole with a 3mm (1/8") drill bit. If you hit a stud, continue drilling the entire length of the bit. If you hit the hollow part of the wall, enlarge the hole with a 10mm (3/8") drill bit for anchors. Fasten the top track with a screw and tighten it enough to hold the top track against the wall. Place a leveller on the top of the top track and adjust it as required. Mark all remaining holes. Step 2 (Hang in the hang standards): Hang in the hang standards onto the bottom "lip" of the top track. In order to fit in the hang standards into the top track, aim for an entry point where there is a cut-out on the upper lip of the top track. Slide the hang standards to their approximate position on the top track. With the end stop at the outer edges of the top track, the hang standard can be placed at the far end of the track. Step 3 (Adding the extension hang standards): Separate out the screws from the extension hang standard adapter. Bend out the hang standard slightly from the wall and slide the top part of the extension standard adapter into the standard from underneath. Fasten the adapter with one of the screws by using a screwdriver. Slide the small, colour-matching, plastic piece and the extension standard onto the adapter. Fasten with the remaining screw . Step 4 (Mounting the brackets): Assemble the brackets into the hang standard by leaning the "nose" of the bracket upwards and attaching the upper "teeth" of the backside of the bracket into the slots. Then let the bracket come down. Step 5 (Mounting the wire shelf): A wire shelf has a top and a bottom. The middle support wire is connected to the bottom of the shelf. Place the bottom of the wire shelf over the notches in the bracket. Install the shelf with end wires inside the brackets. Lock the shelf into place by pressing down on the middle of the shelf and pushing toward the wall. * To reposition a wire shelf after it’s been attached to the brackets: hold by the brackets, and lift the front of the shelf toward the ceiling and outward to release the entire unit from the hang standards. * Demount: To remove a wire shelf from a bracket while on the hang standards: hold the hang standard steady with one hand. Place the other hand at the back of the shelf. Pull up and forward to release. Step 6 (Mounting the closet rod): Insert the closet rod holders into the slot underneath the bracket, by leaning the bottom of the holder slightly upwards and inserting the upper "tooth" of the holder into the slot. The two "flat" closet rod holders are meant to be mounted into the outer brackets. Let the holders come down into place. Once the closet rod holders are mounted, firmly press the end caps into the outer ends of the closet rod. Then snap the closet rod into the closet rod holders.
