If your shelves are less than about 75 cm (2 ft 6 in) long, first fix the brackets to the shelf. For longer shelves, mark the bracket positions on the shelf and then the wall. Fix the brackets to the wall, then attach shelving.
Short Shelves
- Using screws that won't penetrate the top of the shelf, screw the brackets to the underside of the shelf at your chosen spacing.
- Hold the shelf against the wall where you plan to fit it, and rest your spirit level on top.
- Get the shelf level and use a bradawl to mark the wall through the screw holes in the brackets.
- Set the shelf aside. Drill the holes and insert wall plugs.
- Hold the shelf back in place and drive in the top screw in each bracket, then the bottom screw.
Long Shelves
- Mark the bracket positions at your chosen spacings on the edge of the shelf; you are likely to need at least three brackets.
- Hold the shelf flat against the wall with its rear edge in line with the proposed fixing position.
- Mark the bracket positions vertically on the wall, using the marks on the shelf as a guide.
- Hold the first bracket in position so you can mark the wall through its screw holes.
- Drill and plug the holes, then screw the bracket into place.
- Rest the shelf on the bracket with a spirit level on top. Get the shelf level - you may need help with this part. Draw a horizontal pencil mark on the wall where the lower back edge of the shelf meets each of the bracket position marks you drew in step 1.
- Lift the shelf away and fix the remaining brackets to the wall.
- Finish the job by replacing the shelf on the brackets and screwing them to its underside.
