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 inch (41.28 mm) long, shallow, double crimp that replicates factory indentations and ensures a tight fitting, leak-proof connection.
