New Wave Gutter Guard is designed to keep large debris and small animals out of the gutter system. New Wave Gutter Guard offers great protection with raindrop-shaped openings that can handle up to 40 gallons of water per minute based on its unique design. This makes New Wave the best-punched aluminum product on the market. Installed at an angle, it sheds most debris naturally and takes the guesswork out of cleaning your gutters.
