This 48-inch Johnson Structo-Cast level is a durable hand tool designed for precision work across woodworking, cabinetry, framing, and tile alignment. The non-conductive Structo-Cast frame won’t scratch fine wood or painted surfaces, making it ideal for projects where surface protection matters. The three acrylic vials provide readings at different angles for accurate leveling work.
Job site durability and quick maintenance are built in. The impact-resistant acrylic vials resist cracking and deliver easy-read visibility. Quik-Change replaceable vial covers minimize job downtime by allowing quick vial replacement without removing the entire unit.
