About K-Guard™ of Central Ohio




Our Legacy: The Knudson Manufacturing Story
It’s 1997 – The Birth of K-Guard™: A Revolution in Gutter Systems
In 1997, Knudson’s vision and expertise culminated in the creation of the K-Guard™ System, a fully engineered, two-piece leaf-free system. This innovative design, which received its patent and signed its first licensee in 1998, has been delivering unparalleled drainage solutions ever since.
The K-Guard™ system was a game-changer, featuring a fully supported gutter and hood, plus a highly effective, hidden patented hanger system. Engineered to withstand hail, sleet, snow, and other destructive weather conditions, the K-Guard™ system was nearly indestructible. But the real selling point? It was a leaf-free system, allowing homeowners to put away their ladders and forget about clogs for good.
K-Guard™ Today: Setting the Standard in the Industry
Since its inception, over 35 million feet of K-Guard™ gutters have been installed, providing leaf-free gutter guard solutions and 100% lifetime clog-free warranties for homes across the United States. But what makes K-Guard™ one of the best in the business? Let’s delve into the details.
Why does K-Guard™ rank as one of the best in the business? We say the proof is in the pudding.
- With all the gutters installed (over 35 million feet), there has never been a report of hood loss or removal due to wind.
- Its strength is FEA-verified and includes a five-inch gutter which can hold .70 gallons per foot.
- Its robust all-weather design is secured by 0.027- 0.032-inch thick coated aluminum (3105-H16 to H-24) or 16 and 20 ounce copper that is formed on site.
Our innovative seamless patented design (US Patent 5,845,435) has been proven, field tested and offers dual front and rear drainage passages for improved water collecting and flushing action. The textured hood is fully removable which provides an extra line of defense against extreme conditions (even hail!)
