You will need one of these for every standard that each shelf goes across.
These are the parts that support your shelves!
This bracket will work with 20" deep Shelving and will only work with SuperSlide, Linen and CloseMesh shelving.
The bracket is made of steel with a white painted finish and slots into the wall standards that hang vertically from horizontal hang track. The Shelf then clips into the shelf bracket and will support the shelf from below.
