Use Malco’s 5 Blade Gutter Crimper to produce a crimp that downsizes corners of aluminum or steel downspout. The blades on this versatile hand tool produces a 1-1/4 inch (31.75 mm) long double crimp without deforming the downspout wall. The factory-like crimp produced by this tool ensures that the downspout walls stay 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.
