Product Information

Full details

The Kayflow Round Gutter Stop End (112mm) is an essential component for homeowners and contractors looking to securely terminate their rainwater drainage runs. It provides a reliable, watertight seal for 112mm round guttering systems, ensuring water is directed correctly toward downpipes rather than leaking at the gutter terminus. While highly durable and easy to install, users should ensure their existing gutter system is compatible with the 112mm standard before purchase to avoid fitment issues.

FAQs

Is this stop end compatible with other brands of 112mm guttering?

While it is designed for the Kayflow system, it is often compatible with other 112mm round profiles, but a perfect seal cannot be guaranteed outside of the Kayflow range.

Does this product require glue?

No, it is a push-fit component designed for easy installation, though exterior-grade gutter sealant can be used for extra peace of mind.

Will the black color fade over time?

The component is UV stabilized to resist fading and degradation under normal sunlight conditions.

Can this be used on a deep-flow gutter?

No, this is specifically sized and shaped for standard 112mm round profile gutters only.

How do I know if I have a 112mm system?

112mm is the standard diameter for most residential round guttering. You can verify this by measuring the width across the open top of the gutter.

Is this product rust-proof?

Yes, it is made of high-quality plastic and will not rust or corrode like metal guttering components.

Troubleshooting

The stop end feels loose after installation.

Check that the gutter end is cut at a perfect 90-degree angle. An uneven cut prevents the internal rubber seals from engaging fully.

Water is dripping from the seam.

Ensure the stop end is pushed fully home onto the gutter profile and consider applying a dedicated gutter sealant to the interior connection point.

Difficulty pushing the unit onto the gutter.

Ensure the gutter profile is not deformed. If the gutter has been crushed or bent, reshape the end gently before attempting to re-fit the stop end.

Pros and Cons

Pros

  • Quick and straightforward installation process
  • Provides a secure, leak-proof termination for drainage runs
  • High-grade weather-resistant plastic construction
  • Matches standard 112mm round gutter systems
  • Low-maintenance finish that resists fading

Cons

  • Not compatible with square-profile gutter systems
  • Requires proper cleaning of the gutter end for the seal to set
  • Color is restricted to black

Setup, Compatibility & Care

To install, ensure the end of your 112mm round gutter is clear of debris and cut cleanly. The stop end can be pushed directly onto the gutter end; some users may apply a thin bead of gutter sealant for added security in high-flow areas. This product is strictly compatible with 112mm round systems and is not interchangeable with deep-flow or square-line profiles. For care, simply wash the exterior with soapy water during routine gutter cleaning to remove dirt and lichen buildup. Avoid using abrasive cleaning pads that could damage the finish.
