6-Inch GutterBrush Gutter Guard – Fits Large Residential & Small Commercial Gutters (5.25 Inch Diameter)

6-Inch GutterBrush Gutter Guard

Fits Large Residential & Small Commercial 6-Inch Gutters

GutterBrush is a simple, heavy-duty gutter guard designed to keep larger 6-inch gutters flowing freely while blocking leaves, pine needles, roof grit, and debris. The oversized cylindrical brush installs directly inside the gutter, allowing water to pass through while helping prevent clogs in the gutter channel and at downspouts.

The 6-inch GutterBrush is ideal for homes and buildings with higher rooflines, longer gutter runs, steeper roof pitches, or increased water volume, where standard 5-inch gutters may not provide sufficient capacity.

How It Works

Dense, flexible polypropylene bristles form a protective barrier that blocks leaves and debris while still allowing rainwater to flow freely through the brush and into the gutter. Because GutterBrush installs inside the gutter—not on top—there’s nothing to lift, blow off, or become dislodged during heavy rain or wind.

Easy DIY Installation

• Installs quickly with no tools or fasteners required
• Slides directly into the gutter channel
• Bends easily around corners and transitions
• Compresses slightly for a secure fit
• Can be removed and reinstalled for seasonal maintenance

Materials & Durability

• UV-protected polypropylene bristles
• Galvanized steel wire core
• Rust-resistant, weather-resistant, and reusable
• Performs in rain, wind, snow, and ice

Built to handle higher water volume and year-round exposure in demanding conditions.

Designed for Higher-Capacity Gutters

Larger gutters are commonly used to manage increased water flow from steep roofs or wide roof surfaces. The 6-inch GutterBrush provides full-channel coverage to help prevent debris buildup that can restrict drainage and cause overflow or downspout blockages.

Low-Maintenance Protection

GutterBrush significantly reduces the need for frequent gutter cleaning by helping keep large debris out of the gutter system. In areas with heavy leaf drop or pine needles, occasional inspection or brushing off may be recommended.
