The bracket will be mounted over the top of the knee/pony wall. The knee wall bracket is sized in length tip to tip. Start by measuring from the outer edge of your countertop, including the 4 inches for the knee/pony wall. For example, a 12-inch countertop overhang, plus the 4-inch knee wall gives us 16 inches.
This subtraction is to stay away from the outer edge of the countertop, which is usually 2-4 inches. This measurement would be 13 inches (12 + 4 - 3 = 13), thus you would need to order a 12-inch Heavy-Duty Contractor Grade Countertop Support Bracket.Note due to supply chain challenges this product does not contain screws: Recommended hardware is QTY(4) 2 #12 wood screws.
