A & M Hardware Inc. introduces  A.D.A brackets for work stations, countertops and storage shelves. Designed for applications requiring a hidden support, the brackets feature extra strong 1/4" steel construction. The vertical leg of the bracket is bolted to the side of the stud, while drywall is fastened to studs, concealing the vertical leg. All welds are on the reverse side for easy installation, says the company. Support arm lengths are available in 9 inch, 12 inch, 18 inch and 24 inch sizes in standard black or white powder coat with wall mounting hardware included.
