Use the Malco™ C4R Crimper to produce a crimp that downsizes corners of aluminum or steel downspout to create a male connection for joining downspout sections. The five blades of this versatile job-site hand tool produce a 1-1/4 in (31.75 mm) long double crimp without deforming the downspout wall. This factory-like crimp ensures that the downspout wall stays square for 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™ C4R 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.
