External 90° Corner Trim for EPDM Kerb & Drip Edge Systems

Sure Edge External Kerb Corner is a purpose-made trim designed to finish external 90° roof corners where Sure Edge Kerb Trims meet, or where a kerb trim meets a Sure Edge Drip Trim.

This is the most commonly used corner in the Sure Edge system, providing a clean, consistent finish at visible roof edges.

Ideal for EPDM rubber roofing installations where the roof perimeter turns outward.

When It’s Used ▸

Where two kerb trims meet at an external 90° corner
Where a kerb trim meets a drip trim on an outer corner
On roof perimeters that turn outward

Completes the edge detail and ensures a neat, colour-matched finish across the full roof perimeter.

Installation ▸

Install kerb and/or drip trims fully
Slide the external corner over adjoining trim ends
Apply a small amount of super glue to one inner edge only

Important: only bond one side. Fixing both sides prevents movement for expansion and contraction, which may cause cracking over time.

Available Colours ▸

Black
Anthracite Grey
White

Designed to match the Sure Edge trim range for a seamless, professional finish.

Roofer’s Perspective ▸

External corners are the most visible part of any flat roof edge, so they need to be done properly.

This trim gives a clean, consistent finish and avoids rough cut joins that stand out. It also allows for movement without stressing the system.

If you're using Sure Edge trims, this is what finishes the job properly.
