Page 4: Fix the verticals, the brackets and the shelving
It is now simply a matter of screwing the upright battens and/or brackets through the wallboard into the wall studs and placing the shelves. Most clip-in brackets have a little upturned lip at the front, thus keeping the shelf in place. Angle brackets generally have pre-drilled holes to allow for screws to hold the shelves in place. With timber brackets, the shelves can be fixed with screws down through the top of the shelf (drill a hole first) into the bracket.
A light load for 250mm (10") wide x 20mm (3/4") thick solid board shelf is 15kg per meter length (10lb per ft length).
A medium load for 250mm (10") wide x 20mm (3/4") thick solid board shelf is 30kg per meter length (20lb per ft length).
A heavy load for 250mm (10") wide x 20mm (3/4") thick solid board shelf is 45+kg per meter length (30+lb per ft length).
Large books are considered a heavy load.
A solid 20mm (3/4") thick solid board shelf should not span more than 750mm (30") if designed for heavy load.
Note that the above information is a guide only.
