These new Work Station Brackets are unique in that they are adjustable to level once installed. Installation is easily accomplished by cleating the wall with either 3/4" x 1-1/2" or 1-1/2" x 1-1/2" wood pieces. The brackets are butted up to the cleat and the first screw is inserted in the center hole of the bracket. The hole is elongated vertically so minor adjustments can be made. The second screw in inserted in the top hole. The hole is elongated horizontally to allow for side adjustment. The third screw in inserted in the bottom hole. All holes are center of the bracket so for easy location on studs. The two adjusting bolts are tightened once the brackets are checked for level. These brackets are rated to 640 lbs making them great for most countertop installations. Available in both black and white finish.
