Product Information

Full details

The Kayflow Ogee Gutter Union in Black (OGU1BL) is an essential component for homeowners and contractors maintaining or installing the high-capacity Kayflow ogee rainwater system. Designed for roofs up to 105m2, it provides a secure, leak-free connection between gutter lengths while maintaining a traditional scalloped aesthetic. While it offers a convenient tool-free installation process, users must ensure their existing gutter system is strictly 120mm ogee to ensure a proper fit.

Troubleshooting

Visible water leakage at the union joint

Check that the gutter ends are fully inserted and that the internal gaskets have not been displaced during installation.

Gutter length does not clip into the union

Verify that your gutter is indeed the 120mm ogee profile, as this union is not compatible with other profiles.

Difficulty snapping the clips into place

Ensure the gutter section is cut square and clear of any plastic burrs or debris from the cutting process.

Pros and Cons

Pros

Tool-free clip-fit installation saves significant time
High-capacity flow rate supports large roof drainage
Integrated gaskets ensure a watertight finish without extra sealant
BSI Kitemarked for verified quality and safety
10-year guarantee provides long-term peace of mind

Cons

Specific to 120mm ogee gutter profiles only
Cannot be used with standard half-round or square gutter systems
Requires proper alignment for the gaskets to seal effectively

Setup, Compatibility & Care

To ensure a perfect fit, verify that your gutter lengths measure 120mm across the ogee profile. Installation involves cleaning the ends of the gutter lengths to remove any debris or dust, which allows the rubber gaskets to seat correctly. Simply push the gutter ends into the union until the clips lock into place. To maintain the system, periodically inspect the gaskets for signs of degradation and clear any leaves or twigs from the joint area to prevent blockages. The high-gloss finish can be cleaned with a soft cloth and mild soapy water as needed.
