Flat Wall Countertop Support Bracket holds your kitchen countertop firmly in place. This sturdy metal bracket features a non-obstructive design for a floating, seamless look together with your countertop. Its edges are beveled to provide safety against accidental cuts. No corbels are needed. The Flat Wall Bracket is sized in length tip to tip; therefore, a 9-inch bracket is 9 inches from tip to tip. The holes are directly in the middle of the bracket! When determining lengths stay away from the outer edge of your countertop overhang by 3 inches and add the dimensions of the knee/pony wall also. Recommend spacing the brackets every 16-20 inches.
