The One-Man-Rain-Gutter-Tool was designed to allow quick, easy and accurate installation or rain gutters by one person. It is used to hold up each end of a rain gutter during installation. The straight piece on the tool has a notch cut into it, which you can see in the picture. This notch hangs on a nail or screw that is temporarily driven into the house fascia. The wing nut is loosened by hand, allowing the bent segment to raise or lower vertically and lock into the exact position desired, providing the proper slope for the gutter.  NOTE THAT THIS ITEM IS NOT INTENDED FOR USE WITH ANGLED FASCIA.
