This is a variable range. Note that Cabinotch requires you to indicate both “Cabinet Side Height” as well as “Toe-Kick Height” with each applicable cabinet. We then calculate the total cabinet height. *Note that should you select an option for Toe-Kick which includes a leg leveling system that you can make a selection for Toe-Kick Height which will not accommodate the adjustment range of those legs. They max out at a 5” height.
