Before you start: Mount the wallbands and brackets. Step 1: Place the two melamine shelves next to eachother , upside-down, on a flat surface and secure that they are perfectly flush. Step 2: Place the shelf joiners onto the shelves, back and front, with one bore hole on each shelf. Be sure to have the shelf joiners perfectly centered, so that the U-shaped part is straight above where the shelves meet. Step 3: Carefully attach the shelf joiners with the screws. Step 4: Turn the joined shelves with the right side up and lower the joint part (with the U-shaped part of the shelf joiners) into the bracket. Step 5: Fasten the rest of the shelves into the other brackets using bracket screws. Tip: In order to avoid cracks in the shelf, it might be a good idea to pre-drill the shelf with a slightly smaller dimension in the bore hole, before attaching the screws.
