Malco Hand Seamers, with die cast zinc jaws, are gentle on painted or coated metal surfaces. These seamers 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 this tool offers, also has an appeal for limited flattening / straightening tasks in light gauge painted steel including edges of auto body panels. Durable construction offers long, dependable service life under normal use. These tools also feature rust resistant nickel plating. Malcos Hand Seamers, with die cast zinc jaws, also feature ergonomic RedLine Handle technology. An Engineered handle opening compliments the natural power stroke of any users hand and maximizes the powerful 7:1 mechanical advantage of compound-leverage head to handle linkage.
