Brackets are securely welded to the mounting plate for greater durability. Because mounting plate is welded to the bracket, it is much easier to align and install to a wall. The back of the shelf is within a fraction of an inch from the wall to save space. Chromate shelf caps included to cover openings in tops of shelves. Available in chromate or green epoxy coated. Use single brackets at shelf ends and double brackets for adjoining shelves. Hardware to mount brackets to wall is NOT included.
