Troubleshooting

Water leaking at the joint

Ensure the gutter ends are pushed fully into the union bracket and that the rubber seal is seated correctly. Verify that the guttering is not warped or damaged at the join.

Bracket will not snap shut

Check that the gutter ends are correctly aligned and not obstructed by debris. Ensure you are using the correct 112mm half-round profile.

Pros and Cons

Pros

  • Simple, tool-free installation for the joining mechanism
  • Pre-installed rubber seal prevents common leakage points
  • High-quality construction meeting industry standards (BS EN 607/EN 1462)
  • External wings provide excellent accessibility for secure fixing

Cons

  • Compatible only with 112mm half-round profile guttering
  • Requires proper alignment of gutter ends to ensure the seal functions correctly
  • Not suitable for heavy-duty commercial or industrial applications

Setup, Compatibility & Care

To install, ensure your gutter ends are cut square and are free from debris or jagged plastic edges. Align the two gutter lengths within the bracket, ensuring they are pushed fully into the seating area against the internal seal. Secure the bracket through the fixing wings to the fascia board. Maintenance is minimal; periodically clear leaves and organic matter from the internal channel to prevent blockages. If the joint is ever disassembled for repairs, inspect the rubber seal for signs of perishing or damage before re-installing.
