External 90° Corner Trim for EPDM Gutter Drip Edges
Sure Edge External Drip Corner is a purpose-made trim designed to finish external 90° corners where two Sure Edge Gutter Drip Trims meet.
It neatly covers the exposed junction, creating a clean, colour-matched finish at the gutter edge while protecting the underlying trim detail.
Used correctly, it completes the EPDM roof perimeter and ensures a consistent, professional appearance.
When It’s Used ▸
- Where two drip trims meet at an external 90° corner
- On outward-facing gutter edge corners

Installation ▸

Roofer’s Perspective ▸
External drip corners are one of the most visible parts of the gutter edge, so they need to be finished properly.
This trim covers the join cleanly and keeps everything looking consistent, while still allowing for movement in the system.
It’s a small detail, but it makes a big difference to the final result.
