Page 2: Bracket options
Three widely used bracket systems are:
 Wooden braced brackets fixed to vertical battens
L-shaped metal brackets fixed to the wall studs
Metal brackets that clip into slotted metal strip fixed to the wall stud.
Wooden brackets fixed to vertical battens
A wooden shelf bracket comprises of a horizontal piece of wood screwed or nailed to the side of a vertical batten that is fixed to the wall. The horizontal piece of wood is propped by another piece of wood fixed to the underside of the front of the horizontal member and angling down to the vertical batten.
A wooden shelf bracket can be made out of varying size wood such as 45x20 (3/4"x 1-1/2") or 65x20 (3/4"x 2-1/2") or bigger.
L-shaped metal brackets fixed to the wall studs
L-shaped metal brackets come in varying sizes and styles, and achieve maximum strength if screwed directly through the wallboard and into the wall stud.
Summary of appropriate weights for each brackets are:
(a) Metal plate bracket: depending on the thickness of the plate, medium to heavy strength.
(b) Metal plate braced bracket: heavy strength.
(c) Pressed-steel bracket: light to medium strength.
(d) Ornate bracket: depending on thickness of metal and brace, light to heavy strength.
Metal brackets that clip into slotted metal strip fixed to the wall stud
This system achieves maximum strength if the vertical slotted metal strips are screwed directly through the wallboard into the wall studs. The metal strips come in varying lengths as do the brackets that slot into them. This is probably the easiest system to install and the brackets are also adjustable, however it is also the most expensive.
