发明名称 GUTTER PUNCH
摘要 <p>A gutter punch device (10) is positioned over the water collecting opening of the gutter and is adapted to punch the front and rear sheet metal portions of the gutter. The punched holes are made prior to the hanging of the gutter and are used to receive the gutter fastener for securing the gutter to the fascia board of the structure. The gutter punch (10) can be a double throw (Fig. 1) or single throw device (Fig. 5) and enables perfect alignment of the front and rear mounting holes for gutters in an easily reproducible manner.</p>
