Malco Hand Seamers, with die cast zinc jaws, are gentle on painted or coated metal surfaces and are ideal for making clean and accurate bends and seams in aluminum roof flashing, coil stock or fascia. The Jaws feature depth graduations in 1/4 inch (6.35 mm) increments to a maximum 2-inch (50.8 mm) bending depth. The jaws of these large die cast seamers are bowed so that they will hold firmly and evenly across the entire jaw width even when engaged on very light material. The large surface coverage of these jaws also has an appeal for limited flattening / straightening tasks in light gauge painted steel including edges of auto body panels. These Seamers are not warranted for use as a striking tool or for prying or bending heavy ferrous sheet metal. Durable construction offers long, dependable service life under normal use. These tools also feature rust resistant nickel plating.
