RAIN FLOW is a permanent solution that prevents clogged gutters and eliminates the problems of traditional screens and metal covers. Water flows freely through this latex-coated natural fiber material; but leaves, seeds and other debris stay on top to blow away on the next breezy day. No screws, nails, brackets or caulk are needed for installation. Rain Flow cuts with scissors and is invisible from the ground. It fits 5- and 6-inch K-style gutters, providing high profits and easy installation. For more information, call 800-796-4476 or visit www.rainflowusa.com.
