Use the Malco C5R Crimper to downsize stove pipe and round metal duct to create a male connection for joining sections. The five blades of this versatile job-site hand tool produce a 1-5/8 inch (41.28 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.
