This is for one (1) knee wall bracket made of  1/2" thick by 2.5 " wide American steel. Countersunk hole diameter - 1/4 ". Brackets coated with Rust-Inhibitor Paint. When determining length to use: stay away from outer edge of your countertop by 3 inches and add the dimensions of the knee wall or pony wall also. For example: a 12-inch countertop overhang and a 4-inch knee wall, minus 3 inches = 13-inch bracket, therefore, you would order a 13 bracket with this example. We recommend spacing your brackets 20 inches apart for maximum protection for your granite or stone countertop. Made in the USA.
