Step One
-
Safety
Use a wire/pipe power detector to ensure that there are no electrical cables
or water pipes where you intend to position the shelf.
Use a tape measure and spirit-level to mark the vertical position for your
shelf bracket with a pencil. Your mark should be for the top of the shelf
bracket and bottom of the shelf bracket.
Step Two
-
Vertical positioning of your shelves
Use the spirit level and a pencil to draw a perfectly horizontal line along the
area of the wall where you intend to mount the shelf. If your spirit level has
a measure on it, draw the line to the full length of the shelf. If not, use a tape
measure and redraw the line a couple of times, until it is the same length of
the shelf.
Step Three
-
Draw a level line
Decide where to position the brackets and mark these positions on your
horizontal line. Focusing on one bracket at a time, place the top of the
bracket up to horizontal line and centre on your positioning mark. Keeping
the bracket perfectly still, use a pencil to mark the screw holes on the wall.
Repeat this for each of the brackets.
Step Four

Mark positions for the shelf brackets
