Malco hand seamers, with forged steel jaws, are the premier choice for bending, folding, flattening and straightening sheet metal edges or safely gripping and moving sheet metal around the jobsite. Malco's hand seamers, with forged steel jaws, also feature ergonomic Redline handle technology. An engineered handle opening compliments the natural power stroke of any user's hand and maximizes the powerful 7:1 mechanical advantage of compound-leverage head to handle linkage. Comfortable handle grip contours, a non-slip grip insert, spring handle actuation and a thumb-operated handle latch ensure a natural fit and feel for comfortable one hand operation anywhere on the job.
