You need the following to assemble: Screwdriver/drilling machine, metal saw (if adjusting wallband heights), leveller. Before you start: Make sure you have chosen the right screw/plug for your wall type. The recommendation, when mounting wallbands, is to use Elfa hardware. We recommended that a screw should be placed in every hole, for maximum safety. 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: Position the first wallband where you want it on the wall. Mark the position of the second screw hole from the top of the wallband. Step 2: Drill a hole. If you hit wood, continue drilling the entire length of the drill bit. If you hit a hollow part of the wall, enlarge the hole with the appropriate drill bit size for  the type of hardware needed for your wall surface. Screw the wallband loosely into place. Step 3: Using a leveller, check that the wallband is straight. Mark and drill the remaining holes and fasten all of the screws. Step 4: To install the next wallband, measure and mark out a suitable distance between the two wallbands, based on your plan. Repeat for each additional wallband. Tip: While holding the unattached wallband to the wall, place a shelf on the brackets. Adjust the spacing as needed and check that the shelf is level.
