You need the following for installation: Screwdriver/drill, metal saw (if adding top tracks and/or adjusting the width), spirit level Before you start: Make sure you have selected the correct screw and plug for your wall type. When installing the top track, we recommend using Elfa screw and plug. We recommend placing one screw in each hole for maximum safety. The screw holes in the top track are oval to increase the likelihood of hitting wall studs. Important! Be careful not to drill into electrical wiring, ventilation ducts, pipes, or other sensitive installations. If you are unsure where these are located, contact a professional electrician or plumber before drilling. Step 1: Place the top track at the desired height and mark a hole in the centre. Step 2: Start drilling the marked hole using a 3 mm (1/8") drill bit. If you hit a stud, continue drilling to the full depth of the drill bit. If you hit a hollow wall, enlarge the hole using a 10 mm (3/8") drill bit for drywall anchor. Step 3: Secure the top track with a screw and tighten enough to hold it against the wall. Place a spirit level on top of the top track and adjust if necessary. Mark the remaining holes. If you want to connect two top tracks: Start by mounting the longer section furthest to the left. Before mounting the connecting top track, you need to saw off the stop on the left side – there is a mark 28 mm (1-1/8") from the edge on the back showing where to cut. Use a metal saw for a clean cut. When joining two top tracks and there is no space for overlap (e.g. wall‑to‑wall installation), the added top track must be cut (we recommend cutting the left side). The minimum possible width for a cut top track is 184 mm (7-1/4"). In this case, the cut must be made at each end so that two screw holes remain. When cutting a top track, make sure the cut is at least 3 mm (1/8") away from any screw hole or slot.
