Use the Malco C6R Crimper overhead or in tight working quarters to downsize stove pipe and round metal duct and create a male connection for joining sections. Offset handles keep hands off work obstacles such as floor joists and underlayment while promoting correct hand orientation for gripping. The five blades of this versatile job-site hand tool produce a 1-5/8″ (41.3 mm) long, shallow, double crimp that replicates factory indentations and ensures a tight fitting, leak-proof connection. The connection is also more self-supporting during installation. A handle closing stop maintains a consistent crimp profile. Hardened all-steel construction and a nickel chrome finish ensure long service life. The Malco C6R Crimper also features 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.
