The Drip Edge Hemming Tool allows you to make quick, easy, uniform bends along the drip edge of a flat pan, standing seam metal roof panel. Its reinforced steel plates create the ideal fit for folded bends and can be set to 3/4, 1, 1-1/4, or 1-1/2 inch depths thanks to adjustable bolts and pre-marked holes. The ergonomic handle offers comfortable leverage for easy use and is also removable for easy packing. Contact surfaces are coated to prevent finishes from marring and scratching. The Hemming Tool also has convenient pre-marked measurement lines that allow you to cut the plates to fit your panel from 18-inch widths down to 12-inch widths. Recommended for a Maximum of 22-gauge steel.
