What makes the K-Guard Gutter System so effective at keeping dirt, sticks, other debris, and pests out? Our system is a full and complete clog free gutter system unlike most other gutter protection options. Our system includes a curved hood to allow leaves and debris to slide off the gutter rather than getting trapped inside, 5 inch gutters that allow for more water to move through the system, and larger sized downspouts that eliminate clogs.
