Putting up that shelf can be every diyer’s nightmare, whether it is in the home, shed or garage but it need not be so if a few simple instructions are followed
There are numerous systems and types of shelving supports but we are discussing here using the traditional bracket often referred to as London Grey Bracket which are finished in grey and are paintable to match décor. They are a strong bracket which can support up to 20kg but the method of securing the bracket depends on the construction of the wall and on the weight of the items on the shelf.
Normally the longer leg of the bracket is fitted to the wall and the shorter to support the shelf. E.G. paperback books a 5x4 bracket is suitable and a 12x10 bracket for a 12” shelf for lever arch files. As a rule of thumb the bracket leg supporting the shelf should be a minimum of 2/3rd the width of the shelf e.g. a 12” shelf would need 10” brackets
While the width of the shelf will determine the size of the bracket required and the length of the shelf determines the number of brackets e.g. a 36” long shelf would need at least 2 brackets or more depending on the loading. 72” at least 4 brackets. For heavy items just fit more brackets.
When establishing the position, if critical, allow for the thickness of the wooden shelf
Check for electrical cables and pipes BEFORE drilling holes
Find the position of the wall support studs using a stud finder or lightly tap the wall and the sound will change when the stud is located Fixing into the plasterboard using wing toggles or speed plugs is not recommended as the carrying capacity will be dramatically reduced
For smaller brackets use a pozidrive countersunk screw size 4.0mm (No8) x 40mm (1-1/2”) or 50mm (2”)
But for larger brackets use a pozi drive countersunk screw size 5.0mm (No10) x 50mm (2”)
Mark the position of the holes in the first bracket and after fixing use a level to make sure your planned bracket locations are along a straight, level line. This will ensure your shelves are level after installation.
