Coninx External Gutter End Cap, 125mm uPVC, UV Resistant

Coninx Gutter End Cap

The Coninx External Gutter End Cap provides a secure, watertight seal at the termination point of a roof drainage run. This component prevents water from bypassing the gutter system and damaging the building fascia or foundation. Manufactured from high-grade uPVC, this fitting withstands harsh environmental conditions and heavy rainfall cycles. It is designed specifically for the standard 125mm profile used in residential and commercial construction across the region.

Built for the Job

Contractors install this stop end at the highest point of a gutter run or at any termination point where a downpipe is not located. It manages the flow of rainwater effectively by containing it within the trough. Site supervisors specify these fittings because they handle the thermal expansion and contraction cycles common in tropical climates. The external fitment allows for a clean finish on the outside of the gutter profile. This design facilitates easy inspection and maintenance without needing to dismantle the entire drainage run. Plumbers frequently use this part in rainwater harvesting setups to ensure maximum collection efficiency by preventing leaks at the run ends.

• Closing off gutter runs on residential gable ends and eaves.

• Terminating drainage systems on commercial warehouse roofing.

• Managing water flow in multi-unit housing development projects.
