Upgrade Your Gutter Protection with DuraFlo High Flow Panels

Handle More Water, Fewer Callbacks

If you’re installing gutters in areas with steep pitches or high rainfall, your standard hood guard may not be enough. The Hallett DuraFlo High Flow Panel is built to solve that. It combines the strength and reliability of the original DuraFlo system with an added top panel of 3/16” diamond-shaped openings for even greater water intake.

It’s built to fit both 5-inch and 6-inch K-style gutters, and installs quickly over existing systems. With a reverse S-curve and under-shingle design, this guard delivers premium water control while keeping debris out.

What Makes DuraFlo High Flow Different?

  • Enhanced water intake — The added perforated section helps move water into the gutter faster, even during downpours

  • Reverse S-curve design — Helps direct water smoothly into the trough while deflecting leaves and debris

  • Installs over existing gutters — Quick, secure install with included painted screws

  • Made from 0.024 gauge aluminum — Durable and built to last

  • Recommended for 4/12 to 8/12 roof pitches

Whether you’re dealing with heavy rainfall or steep rooflines, this system is made to handle it.
