Step 1: Use a soft pencil and spirit level to mark the space on the wall (top and sides) of where you want the shelf to go.
Step 2: Locate the drill hole centres for the wall anchor. If fixing to a hollow wall, screwing anchors directly to wall studs is the best way. Use your stud finder to locate two studs where the shelf can be mounted, and mark them with a soft pencil. If hanging to a solid brick or concrete wall, use masonry anchors.
Step 3: Drill holes in the wall for the anchors. Insert the anchors into the holes.
Step 4: Align your bracket with the anchor holes. Attach the bracket to the wall using screws or anchors.
Step 5: Slide shelf onto the bracket.
