“Magnetic box levels stick to steel, cast iron, and other ferrous metal surfaces to provide readings while keeping hands free to reposition components and materials. They are commonly used when leveling metal pipe, ducts, studs, doors, windows, and shelves. Their frame is long with flat ends and square edges that provide better protection of the spirit vials, greater durability, and more resistance to twisting and bending than the flanged frame of I-beam levels. Its length allows more accurate readings across longer distances than shorter frame of torpedo levels.” has been added to your cart. View cart
