Product Information

Full details

The Lindab 125mm Self-Locking Stop End is designed for professional contractors and DIY homeowners seeking a durable, eco-friendly solution to cap off their steel guttering runs. This component offers the key benefit of a tool-free, self-sealing installation thanks to its integrated EPDM rubber seal, though it is specifically engineered for compatibility with the 125mm Lindab Rainline steel system and may not fit other gutter profiles.

FAQs

Can I use this on 100mm or 150mm gutters?

No, this specific stop end is sized precisely for the 125mm Lindab Rainline system.

Do I need to apply silicone or sealant?

No, the integrated EPDM rubber seal is designed to create a watertight fit without the need for external sealants.

Is the black finish painted or powder coated?

The finish is a durable, factory-applied coating intended to withstand harsh weather without discolouration.

Will this rust if I live near the coast?

The 275g/m2 zinc coating provides significant protection against corrosion, though regular cleaning of salt deposits is recommended for coastal areas.

Can I reuse the stop end if I make a mistake?

Yes, it can be removed and repositioned, provided the locking tabs and rubber seal are not damaged during removal.

Troubleshooting

Stop end feels loose after installation

Ensure the gutter end is square and free of debris. Remove and re-seat, ensuring the locking clips have engaged fully.

Difficulty tapping the stop end into place

Check that the gutter profile has not been deformed during cutting; use a pair of pliers to gently correct the gutter shape if necessary.

Leaking at the junction

Verify the EPDM rubber seal is not pinched or folded; ensure the gutter edge is smooth and free of sharp burrs.

Pros and Cons

Pros

  • No sealant or special tools required for installation
  • Exceptional durability with a 70-year life expectancy
  • Eco-friendly steel construction with low carbon footprint
  • Universal left/right hand compatibility
  • Minimal thermal movement compared to plastic guttering

Cons

  • Compatible only with the Lindab 125mm Rainline range
  • Requires careful alignment to ensure the seal sets properly
  • Cannot be used on PVC or cast iron guttering systems

Setup, Compatibility & Care

To install, ensure your Lindab 125mm gutter length has a clean, straight edge. Do not attempt to use this product with other brands of guttering as the locking mechanism is proprietary. For maintenance, simply inspect the end annually during gutter cleaning to ensure the rubber seal remains intact and the steel finish has not been compromised by physical impact. Should the finish be scratched during installation, treat the area with a matching touch-up paint to maintain the anti-corrosive properties of the zinc coating.
