Save yourself effort and frustration while installing outdoor holiday lights this year, and use your extra time to enjoy the view. These plastic S-shaped fasteners roll easily onto your rain gutter and hold strings of lights firmly in place all season long, eliminating the need for annoying twist ties or unreliable hooks. The manufacturer recommends placing one gutter hook every 2 feet when stringing lights.
