This hanger is designed for on the roof installation. If you lack a fascia board, or have a steep roof pitch, a roof mounted hanger is recommended. Most of our hangers are made of the same material. These hangers are super strong. You need to use a hanger bender to bend the shaft to the correct angle. It is a quick installation where you place the back edge of the gutter into the hanger, and simply push the bead in and down into place. The hanger is tested to the highest standards and strength classification available.
