Product Information

Full details

The Lindab Gutter Straight Overflow Protector is an essential component for homeowners and contractors looking to manage high-volume rainfall on buildings with steep roof pitches or inadequate drainage. It excels at preventing water spillover, effectively directing flow into the gutter system to safeguard your property’s foundation and siding from splashback, though it requires precise alignment with your existing 125mm gutter profile to function optimally.

Extended Product Information

FAQs

Will this fit a 150mm gutter system?

No, this product is specifically engineered for 125mm gutter systems.

Is the Anthracite Grey finish weather-resistant?

Yes, the polyester paint finish is specifically formulated to resist UV fading and harsh weather.

Can I install this on an old copper gutter?

It is not recommended, as mixing galvanized steel with dissimilar metals like copper can lead to galvanic corrosion.

How often should I clean the protector?

It should be inspected annually during your regular gutter cleaning routine to ensure no debris is trapped behind it.

Does this product require special tools for installation?

Standard gutter installation tools are usually sufficient, though a drill and appropriate fasteners may be needed depending on your specific gutter setup.

Troubleshooting

Water still overflowing behind the protector

Check the seal between the protector and the gutter edge; ensure it is properly seated and tightened.

Protector appears loose after installation

Verify that your gutter clips are tight and that the protector is fully hooked over the bead of the gutter.

Discolouration or rust spots appearing

Inspect for deep scratches in the paint; touch up with matching anthracite paint to prevent the base steel from oxidizing.

Pros and Cons

Pros

  • Durable galvanized steel construction
  • Resistant to rust and fading
  • Protects property from water damage
  • Seamless aesthetic with Anthracite Grey finish
  • Easy to integrate into 125mm systems

Cons

  • Limited to 125mm gutter sizes
  • Requires proper alignment for maximum efficiency
  • Professional installation recommended for optimal sealing

Setup, Compatibility & Care

Installation should be performed while the gutter system is clean and dry. Ensure the protector is securely fastened to the top edge of the 125mm gutter to create an effective damming effect without obstructing the flow path. Because the unit is made of galvanized steel with a protective paint finish, avoid using abrasive cleaning pads or harsh chemicals that could scratch the coating. Periodic inspection during spring and autumn—especially to clear debris—is sufficient to keep the protector in top condition. Compatibility is strictly limited to 125mm Lindab-style guttering; do not attempt to force fit this onto undersized or oversized systems.
