The LEVEL5 Classic Flat Box is designed to simultaneously apply joint compound while feathering edges for a professional finish. Considered a staple among the automatic taping tools, the classic flat box comes in three different sizes (7-inch, 10-inch, and 12-inch) with an adjustable crown dial that ensures the precise amount of mud. Made from anodized aluminum with a corrosion-resistant red finish, this flat box has a deeper back spine which allows for easier operation. Their lids open extra wide to accommodate easy cleaning.
